Which formula can be used to calculate the molar mass of ammonia (nh3)? molar mass of n + molar mass of h 3 × molar mass of n + molar mass of h molar mass of n + 3 × molar mass of h 3 × molar mass of n + 3 × molar mass of h

Molar mass of N + 3 ×molar mass of H

Explanation:

The molar mass of a compound is calculated by adding the total mass of the individual atoms making up the compound. In NH₃ we have 1 nitrogen atom and 3 hydrogen atoms.

Therefore the total mass of nitrogen in the compound=  1 ×molar mass of nitrogen.

Total mass of nitrogen= 3× molar mass of hydrogen.

If we were to calculate the molar mass of ammonia it would be:

14+ (3×1)= 17

since electrons are negative the answer is neagtaive
