Three different containers contain three different gases with following parameter
Container 1 of 67.2 L containing gas X at `0^@C` and 1.01325 bar
Container 2 of 44. 8L contaning gas Y at 546 K & 760 mm of Hg
Container 3 of 89.6 L containing Z gas at 101325 `N//m^2 & 0^@C`
Now they are mixed in single container. If gram molecular mass of X ,Y & Z are 10 g/mol, 20 g/mol and 40 g/mol respectively Then which of the following statements are correct

Options

A. Mole percent of gas Z in final mixture is 50%
B. Average molecular mass of final mixture is 26.25 amu
C. Mole ratio of gas X and gas Z is 3:4
D. Number of molecules present in final mixture is equal to number of atoms in 320 g Ca
