What is the molecular mass of a gas that has a density of 0.897 g/L if it exerts a pressure of 1.35 ATM and is that a temperature of 43.5°C?

asked by Karla
  1. p*molar mass = density*RT

    Remember T must be in kelvin.

  2. assume 100Liters, mass then is 89.7 grams

    so you have P, v(100lites), n=mass/molmass and you know mass, Look up R for your units, and you know temperature
