Question

What is the mass of
22.4 litres of ammonia​

Answer 1

17g

Step-by-step explanation:

Using the relation :

Volume = mass / molar mass

Volume of ammonia = 22.4 litres

Mole of gas at stp :

1 M of NH3 = 22.4 litres

Chemical formula for ammonia = NH3

The molar mass :

NH3 =14 + (1*3) = 14 + 3 = 17

Volume of ammonia = 1 M

Mass = volume * molar mass

Mass = 1 * 17

Mass = 17g
