Question

PV = nRT Please help me to solve this problem for a lab report. I have most of it figured out already. My work is in the boxes below. Thank you.

4. Calculate the mass of toluene vapor required to fill the distillation flask (50 mL), and the long distillation column (assume a volume of 5 mL for the latter) and a temperature of 110 degrees C, the boiling point of toluene. Given Information Mass of Toluene Vapor: X Distillation Flask Volume: 50mL Long Distillation Column Volume: 5mL BP of Toluene - Temperature: 110°C Pressure (assumed): latm Getting Organized: PV nRT Ideal Gas Constant R Type equation here.

Answer 1

Using ideal gas equation

PV = nRT

n = PV/RT

= 1.0×0.055/0.08206×383

= 0.00175 mol

Mass(X) = n × molar mass

=> 0.00175×92.1

= 0.161 gram
