Question

what is the molar mass of the ionic compound mg3n2? mg3n2 = ? $\frac{g}{mol}$

Explanation:

Step1: Identify molar masses of elements

Molar mass of Mg is 24.31 g/mol, molar mass of N is 14.01 g/mol.

Step2: Calculate molar mass of Mg3N2

For Mg3N2, there are 3 Mg atoms and 2 N atoms. Molar mass = (3×24.31)+(2×14.01).
Molar mass = 72.93 + 28.02 = 100.95 g/mol.

Answer:

100.95
