Which equation is set up correctly to determine the volume of a 3.2 mole sample of oxygen gas at 50°c and 101.325 kpa?

a v=(3.2 mol)(8.314 l⋅kpa/k⋅mol)(323 k)101.325 kpa

b v=(3.2 mol)(8.314 l⋅kpa/k⋅mol)(50∘c)1 atm

c v=(8.314 l⋅kpa/k⋅mol)(50∘c)(3.2 mol)(101.325 kpa)

d v=(3.2 mol)(8.314 l⋅kpa/k⋅mol)(1 atm)(323 k)
