3.49g of ammonia at STP occupies volume of 4.48 dm³ calculate molar mass of ammonia

Open in App

Solution

Dear Student,
We can calculate relative molar mass of the molecule.
Here volume is 4.48dm³ = 4.48 L
Now according to gas law we know that the volume of one mole of gas = 22.4 L
4.48 L of the ammonia gas takes 3.49 gram
So 22.4 L of the gas take = (3.49*22.4)/4.48 = 17.45 gram
So relative molar mass of the ammonia gas is 17.45 gram
Regards
