WebJan 30, 2024 · Solution. To use Raoult's Law (Equation 1 ), we need to calculate the mole fraction of water (the solvent) in this salt-water solution. χsolvent = moles of water moles of solute + moles of solvent. χsolvent = nwater nsolutes + nwater. The molar mass of CaCl 2 if 111 g/mol and of water is 18 g/mol. WebCHEM 162 (Barrows) Chapter 18 Notes Spring 2024 Page 26 of 34 Raoult’s Law Practice Problem: Volatile A + Volatile B Find the total vapor pressure of the solution (P solution) and mole % of the benzene in the vapor of the solution (Υ benzene in vapor) in a mixture (at 20 ºC) of 1.0 mol of benzene & 2.0 mol of toluene.

We calculate mass percentage by mass of component divided by total … WebSo, each mole of the solution will have 0.5 moles of benzene and 0.5 moles of toluene. Now, we have, 1 mole of benzene (C6H6) = 78 gm . so, 0.5 mole of benzene = 78 x 0.5 = 39 gm. Similarly 0.5 moles of toluene (C6H5CH3) will be = 92 x 0.5 =46 gm. Now we know that weight % = mass of component / total mass of solution x 100 done without enthusiasm or interest https://prismmpi.com
