Question

The density of air is 0.00130 g/ml. The vapour density of air will be.

• A. 0.00065
• B. 0.65
• C. 14.4816
• D. 14.56

Answer 1

Answer: (D)

14.56

Answer 2

Density = $\frac { M } { V }$

$d = \frac { v . d \times 2 } { V }$ $( M = V . d \times 2 )$

$V . d = \frac { 0.00130 \times 22400 } { 2 } = 14.56 \mathrm { gm } ^ { - 1 }$
