The Density Of Air Is 0001293 Gcc At Stp Its Chemistry Question

The density of air is 0.001293 g/cc at STP. Its vapour density is

Options

(a) 0.001293
(b) 8.2786
(c) 14.49
(d) 6.2706

Correct Answer:

14.49

Explanation:

At STP, 22.4 litres of gas is equal to 1 mole.
Given density=0.001293 g/cm³
1 mole has 0.001293 gram
22.4 ml has 0.001293 x 22.4/10⁻³
Molecular mass=28.97
Vapour density= Molecular mass/2 = 14.485
