Answer in units of J

2.00 moles of O2 expand from a volume of

3.00 liters to a volume of 5.6 liters against a

constant external pressure of 0.0100 atm?

Answer in units of J

Expert's answer

A = P x deltaV

A = 1.013 x 10^3 x (5.6 - 3) x 2 mol

А = 5.6728 x 10^3 J

A = 1.013 x 10^3 x (5.6 - 3) x 2 mol

А = 5.6728 x 10^3 J
