Question

2 kg of air is at T = 120degreeC and P = 3.5 bar. Find the volume.

Answer 1

Answer:

The Volume is V= 644.89 L

Explanation:

m= 2 kg

T= 120 º C = 393.15 K

P= 3.5 bar = 3.45 atm

R= 0.08205746 atm L / K mol

M= 0.029 Kg / mol

n= m/M

n= 68.96 moles

p*V= m*R*T

V= m*R*T/p

V=644.89 L
