Answer 1

Answer:

We can calculate the relative molar mass of the molecule.

Here volume is 4.48dm3=4.48L

Now according to gas law, we know that the volume of one mole of gas =22.4L

4.48L of the ammonia gas takes 3.49gram

So 22.4L of the gas take =4.483.49×22.4​=17.45gram

So relative molar mass of the ammonia gas is 17.45gram
