Which of the following statements is incorrect?

The atomic masses of carbon,nitrogen,and oxygen are $12, 14$,and $16$ respectively. Which of the following pairs of gases will diffuse at the same rate?

At $100\,^oC$ and $1\, atm$ pressure,the density of liquid water is $1.0\, g\, cm^{-3}$ and the density of water vapor is $0.0006\, g\, cm^{-3}$. What is the volume occupied by water molecules in $1\, L$ of steam at the same temperature in $cm^3$?

At $T \ K$,hydrogen and oxygen gases are mixed in the ratio of $1:2$ by mass in a closed vessel of volume '$V$' litres. If the total pressure of the gaseous mixture is '$p$' atm,the partial pressure of oxygen (in atm) is

The total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases. This is known as which law?
