The ratio of masses of oxygen and nitrogen in a particular gaseous mixture is 1: 4. The ratio of number of their molecule is :
A.7 : 32✓ Correct
B.1 : 8
C.3 : 16
D.1 : 4
Explanation
Let the mass of oxygen is = w And the mass of nitrogen is=4w Number of molecules of oxygen= / 32 A w N x Number of molecules of Nitrogen= 4 / 28 A w N x The ratio of molecules= 28/ 32 4 w w x x =7/32.
