Question

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

• A. PV = (5/32) RT
• B. PV = 5 RT
• C. PV = (5/2) RT
• D. PV = (5/16) RT

Answer 1

Answer: (A)

PV = (5/32) RT

Answer 2

As PV = nRT

$n = \frac{m}{molecularmass} = \frac{5}{32} \Rightarrow PV = \left( \frac{5}{32} \right)RT$
