Chemistry hw ideal gases

Question

A 5.6mol sample of neon gas occupies a volume of 67L at 2.25 atm. Calculate the temperature at which this sample would be. Name the law used

Answer 1

The name of the law is the "ideal gas law".

PV = nRT

P = pressure =2.25 atm

V = volume = 67 L

n = moles = 5.6

R = gas constant = 0.0821 Latm/Kmol

T = temperature in K = ?

Solve for T:

T = PV/nR

Plug and chug to solve for T
