Question

The equation of state for 5 g of oxygen at pressure P and temperature T, occupying volume V, is (R is the gas constant):

G1 Physics · Accepted Answer

Step 1: Ideal-gas equation: PV = nRT. Step 2: Molar mass of O₂ = 32 g mol⁻¹, mass = 5 g. Step 3: Number of moles n = 5/32. Step 4: Substitute into the gas equation: PV = (5/32)RT. Final answer: (A).
