Question

a)At O'C, the density of a certain oxide at 2.0 atm is same as that of dinitrogen
at 5.0 atm. What is the molecular mass of the oxide?
​

Answer 1

answer:-- At 0°C, the density of a certain oxide of a gas at 2 bar is same as that of dinitrogen at 5 bar. What is the molecular mass of the oxide? Hence, the molecular mass of the oxide is 70 g/mol.
