Question

3.49 g of ammonia at stp occupies volume of 4.48 dm3 mass of ammonia. ​

Answer 1

Answer:

dm3 mass ofWe can calculate the relative molar mass of the molecule.

Here volume is 4.48dm

3

=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 =

4.48

3.49×22.4

=17.45gram

So relative molar mass of the ammonia gas is 17.45gram
