Question
The ratio of masses of oxygen and nitrogen in a particular gaseous mixture is 1 : 4. The ratio of number of their molecule is
Options
A.1 : 4
B.7 : 32
C.1 : 8
D.3 : 16
Solution
Let the mass of O2 = x
Mass of N2 = 4x
Number of moles of O2 =
Number of moles of N2 =
∴ Ratio =
= 7 : 32
Mass of N2 = 4x
Number of moles of O2 =
Number of moles of N2 =
∴ Ratio =
= 7 : 32Create a free account to view solution
