Question

Select one correct statement. In the gas equation, PV = nRT

(a) n is the number of molecules of a gas

(b) V denotes volume of one mole of the gas

(c) n moles of the gas have a volume V

(d) P is the pressure of the gas when only one mole of gas is present.

Answer 1

The correct option is : (c) n moles of the gas have a volume V

Explanation:

In the van der Waal's equation
