Answer:
17g
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
