The density of air is 0.001293 gm/ml at S.T.P. It’s vapour density is -

A

`10.0`

B

`15.0`

C

1.44

D

14.4

Text Solution

Verified by Experts

The correct Answer is:
D
d = 0.001293 g/mol = 1.293g/lt
Now `(M_(0))_("air") = (d xx R xx T)/(P) = 1.293 xx 224 = 28.96 " " V.D. = ((M_(0))_("air"))/(2) = (28.96)/(2) = 14.48`
