What is the ideal gas equation for 20 g of gas whose molecular weight is 50g?

Solution
Given, molecular weight of the gas = 50 g
Mass of gas given = 20 g

The ideal gas equation is given by, 

           PV = nRT                      ...(1) 

where n is the number of moles. 

Here the number of moles of gas is, 

                 n=2050=0.4 

∴  The gas equation becomes 

               PV = 0.4RT
