Question

Which of the following gas constant should be used to predict properties of 1 mole of a gas at 1.25 atm?

Group of answer choices

A. 0.0821 atm*L/(mol*K)

B. 8.314 kPa*L/(mol*K)

C. 1.987 kcal/(mol*K)

d. 1.985 BTU*lb/(mol*R)

Answer 1

Since the pressure is I atm, the gas constant must be 0.0821L.atm/K.mol

We must take the unit of pressure into account.
