Question

A gas is found to have a formula (CO)x . If its vapour density is 70,Then value of x is (1) 2 (2) 3 (3) 5 (4) 6

Answer 1

(3)5 is the correct answer

Answer 2

Answer: 5 (3)

Explanation:

V. D x 2 = molecular mass

70x2= 140

M.M of (CO)x = (12+16)x => (28)x

140 = 28x

X = 140/28

X = 5
