Question

Two different gases enclosed in different flasks A and B at same temperature and pressure were found to contain same number of molecules. The ratio of volumes of the flasks A and B must be

(a) 1 : 3

(b) 1 : 1

(c) 1 : 4

(d) 1 : 2

Answer 1

Correct option  (b) 1 : 1

Explanation:

The Avogadro's law states that same volume of all gases at the same temperature and pressure, contain equal number of molecules. Hence, ratio of volumes must be 1 : 1.
