Calculate the pressure of a gas at 295 K if the concentratio

Calculate the pressure of a gas at 295 K if the concentration is 0.150 mol/L.

Solution

pressure = P

moalrity = 0.150 mol / L

T = 295 K

R = 0.0821 L-atm / mol K = universal gas constant

P = M R T

P = ( 0.150 mol / L ) x ( 0.0821 L-atm / mol K ) x ( 295 K )

P = 3.63 atm

pressure = 3.63 atm

1 atm = 101.325 kPa

3.63 atm = 367.8 kPa
