What is the mass of 27.4 L of carbon dioxide gas with a temperature of 30.0 degree Celsius and a pressure of 119 Kpa

Answer 1

First find moles of gas using PV = nRT and solve for n

P = 119 kPa x 1 atm/101.325 kPa = 1.17 atm

V = 27.4 L

R = 0.0821 Latm/Kmol

T = 30 + 273 = 303K

n = ? moles

After solving for n moles, multiply by the molar mass of CO₂ to find the mass of the gas
