At  the density of certain oxide of a gas at bar is same as that of dinitrogen at bar. What is the molecular mass of the oxide?

Solution: The expression for density is .
When the temperature is constant, .
Here, M and P are the molar mass and pressures of nitrogen and M' and P' are the molar mass and pressures of oxide.
Substitute values in the above equation.
