Question

vapour density of a gas having formula (co)x is 70 find out x​

Answer 1

Answer:

5

Explanation:

v.d. 70 m.wt 140 (co). 28 X*28=140. X=5

Answer 2

Answer:

given vapour density =70

atomic weight of C=12 and O= 16

vapour density = molecular weight / 2

70 = (12+16)x / 2

140 = 28x

x = 140/28

x = 5
