Question
A mixture of gases contains H2 and O2 gases in the ratio of 1:4 (w/w).what is the molar ratio of the two gases in the mixture?
-
1:4
-
4:1
-
16:1
-
2:1
Solution
B.
4:1
Let the mass of H2 gas be x g and mass of O2 gas 4x g
Molar H2 : O2
mass 2 : 32
i.e 1: 16
therefore, Molar ratio =
therefore, Molar ratio =
