Q. 1.0 L of $N_{2}$ and 7/8 L of $O_{2}$ at the same temperature and pressure were mixed together. What is the relation between the masses of the two gases in the mixture?
A) ${M_{N}}_{2} = 3{M_{O}}_{2}$
B) ${M_{N}}_{2} = 8{M_{O}}_{2}$
C) ${M_{N}}_{2} = {M_{O}}_{2}$
D) ${M_{N}}_{2} = 16{M_{O}}_{2}$
Explanation
(c)
At constant temperature and pressure, the masses of two gases in a mixture are same, so
${M_{N}}_{2} = {M_{O}}_{2}$
