I assume that your course instructor provided some instruction about how to do this calculation, perhaps as a part of the lab procedure or in an accompanying textbook. If you have access to a lab-focused textbook (I grabbed "Microscale and Macroscale Techniques in the Organic Laboratory" by Pavia, Lampman, Kriz, and Engel), head to the section/chapter on steam distillation for a more complete description.First of all, when a mixture of immiscible liquids is boiled (which is what a steam distillation is), the overall vapor pressure is the sum of the vapor pressures of the two liquids (Ptot = PA + PB). As such, if the vapor pressure of the water was 660 torr at the temperature of distillation, that means the vapor pressure of the organic liquid was 100 torr (since atmospheric pressure is 760 torr, and the mixture will boil when its vapor pressure reaches atmospheric pressure).Next, the mole ratio of the distillate is equal to the ratio of the partia…MoreQuoraQuestionWhat is the chemical formula of steam?Answer · 5 votesChemically, steam is water and hence it’s chemical formula is also [math]H_{2}O[/math].MoreStudy.comQuestionThe condensate from a distillation contains 8.00g of an unknown compound and 18.0g of water.

The vapor pressure of water is 94300Nm^-2 at this temperature. It the atm pressure is 100900Nm^-2,calculate the composition by mass of the distillate?Answer · 0 votesComposition by mass: 31.8% Q and 68.2% H2O.Explanation:The same idea applies here, as well.The number of moles each component of the mixture contributes to the total numbe of moles in the vapor will be proportional to their respective partial pressures.The total pressure at which the mixture boils will be 100900 Nm−2, which means that you can use the vapor pressure of pure water at this temperature to get the vapor pressure of pure Q at this temperaturePtotal=PQ+PwaterPQ=100900 Nm−2−94300 Nm−2=6600 Nm−2This means that you havenQnwater=P0QP0waterSince you need to find the composition by mass of the mixture, multiply both sides of the equation by MM QMM water, the ratio between the molar mass of Q and the molar mass of water, to getnQnwater⋅MM QMM water=P0QP0water⋅MM QMM waterSince you know thatMM=mn⇒m=n⋅MM, you havemQmwater=P0QP0water⋅MM QMM waterPlug in your values to find the ratio between the mass of Q and the mass of water in the mixturemQmwater=6600Nm−…MorePearsonQuestion(b) Calculate the molar mass of a vapor thathas a density of 7.1.Answer · 0 votesHey everyone in this example, we're told that a sample of gas is found to have a density of 1.457 g per liter at 34 degrees Celsius and 8 35 Tour. We need to determine the molar mass of this gas. So we're going to recall our density form of our ideal gas equation and we should recall that that is going to be equal to our density symbol, which is rho equal to our pressure of our gas, multiplied by its molar mass and then divided by the gas constant R. Times temperature. Now, in terms of this question, we need to solve for Mueller mass. So we're going to reorganize this to solve for Mueller mass so that we have Mueller mass equal to our density of our gas, multiplied by the gas constant R. Times temperature and then divided by pressure of our gas. Before we go ahead and plug in our known values. We need to recognize that we're going to have to convert our pressure value from Tour to A. T. M. Because that's the proper unit for pressure in this equation. And we want to go ahead and also co…MoreNumeradeQuestionOne pound-mass of steam behaving as an ideal gas occupies 0.5 ft³ rigid container at 600 °F. The universal gas constant is Ru = 10.732 (psia-ft³) / (lbmol-Rankine) and the molecular weight of water is 18.015 lbm/lbmol. The ideal-gas model is given as Pv = RT where P is the total pressure, V is the volume per unit mass, T is the absolute temperature, and R = Ru/Mw where Mw is the molar mass of the substance. What is the total pressure of the steam, in lb/in² absolute (psia)?Answer · 3 votesso here we will be using ideal gas equation which is pv is equal to nrt where p is pressure v is volume n is number of moles r is gas constant and t is temperature so here this n is what it is number of moles which is also equal to mass divided by molar mass now here we see that pv can also be written as pv is equal to m by capital m multiplied by rt so here we see that this p v by m this is equal to r by capital m so here we have pv p v by m is equal to r by capital m multiplied by t it means that this p v is equal to rt so now we will insert the values of v the of r and the value of t which is the changing temperature in fahrenheit so from here we can find the value of pressure p which will be equal to 1262 .5 psia so this is the value for pressureMoreCheggQuestionOne pound-mass of steam behaving as an ideal gas occupies 0.5 ft3 rigid container at 600 °F.

So composition similar to that of water. First we need to find out the number of mole of steam. So number of mole of steam we have to calculate. Now firstly for that we know that number of mole formula is we have to know the given mass and its molar mass. So given mass is 9 gram. Number of mole is the ratio of mass by the molar mass and molar mass of steam. So steam is nothing but the H2O and its molar mass is 18. So we have to put there 9 divide by 18 which is equal to 0 .5. 1 mole contain Avogadro's number which is 6 .02 multiply with 10 to the power 23. Now here we have 0 .5 mole so which is equal to how many molecules. So it is 6 .025 multiply with 10 to the power 23 multiply with 0 .5 which is equal to 3 .01 multiply with 10 to the power 23 molecules.MoreBrainly.inQuestioncalculate the number of molecule in 5g of steam​Answer · 2 votesExplanation:steam=h2O.molecular mass =1+1+16=18molar mass =18gmol-1no.of moles=mass of substance/molar mass=5/18=0.28molno.of molecules =no.of moles ×avagadros constant=0.28×6.022×10raise to 23=1.69×10raise to 23 molecules.I HOPE IT WILL HELP U.PLEASE MARK ME AS BRAIN LIST.MoreDoubtnutQuestionIn the steam distillation of an organic oil (immiscible with water), the mixture of oil and water boils at 372 K under 1 atm pressure.
