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)

N = 3.2 moles, T = 50 + 273 = 323 K, P = 101.325 kPa, R = 8.314 L. kPa/K. mol

PV = nRT

V = nRT / P substituting.

V = (3.2 mole) (8.314 L. kPa/K. mol) (323 K) / (101.325 kPa)

That is the answer, but it is not among the options you provided. Check your options properly.
