Question
The density of air is 0.001293 g/ml at S.T.P. Its vapour density will be :
Options
A.10
B.15
C.1.44
D.14.4
Solution
Density of air = 0.001293 gm/ml
1 mole of air at STP have 22.4 lit volume
∴ Mass of 1 mole = 22400 × 0.001293 = 28.96 gm
Vapour density =
= 14.48.
1 mole of air at STP have 22.4 lit volume
∴ Mass of 1 mole = 22400 × 0.001293 = 28.96 gm
Vapour density =
