Question

When 1 L of Co2 is heated with graphite, the volume ofthe gases collecTed is 1.5L. Calculate the number of moles of COctober produced considering volumes are measuredoing at STP.

Answer 1

Using the Ideal Gas Law, you would find the volume of 1 mole of a gas at Standard Temperature and Pressure (STP).

STP = 1 atm of pressure and 273 K for temperature

P = 1 atm

V = ???

n = 1 mole

R = 0.0821 atm L/mol K

K = 273 K

PV=nRT

solves to

V=nRTP

V=1mol0.0821(atmL)molK273K1atm

V = 22.41 L of gas @ STP

I hope this was helpful.
