Question #24261

a mass of 88 grams of carbon dioxide will occupy a volume of how many liters at STP?

Expert's answer

STP is standard temperature and pressure, so you need to use PV = nRT

Pressure = 1 atm

Volume = unknown!

n = moles of CO

R = gas constant. 0.0821 L*atm / K*mol

Temperature = 273 K

V = nRT/P = 2*0.0821*273/1 = 44.82 L

Pressure = 1 atm

Volume = unknown!

n = moles of CO

_{2}= m/M_{w}= 88/44 = 2 molesR = gas constant. 0.0821 L*atm / K*mol

Temperature = 273 K

V = nRT/P = 2*0.0821*273/1 = 44.82 L
