WebNov 5, 2024 · N = 14.0067. Next, multiply the atomic mass of each atom by the number of atoms in the compound. There is one nitrogen atom (no subscript is given for one atom). There are three hydrogen atoms, as indicated by the subscript. molecular mass = (1 x 14.0067) + (3 x 1.00794) molecular mass = 14.0067 + 3.02382. molecular mass = … WebSimulations - Discover a new way of learning Physics using Real World Simulations.
