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?
p*molar mass = density*RT
Remember T must be in kelvin.posted by DrBob222
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 temperatureposted by bobpursley
