Question

A 3.33-L flask is filled with propane gas (C3H8), at 1.00 atm and -24.5°C. What is the mass of the propane in the flask?

Answer 1

This problem can be solved using Ideal Gas of Equation (PV=nRT). Solving for mass, mole is expanded to mass/M. mass. Now having all values in hand , convert temperature from celcius to Kelvin. Below is the solution,
