What is the molar mass of the compound Magnesium Nitride? The molar mass of Magnesium (Mg) is 24.305 grams/mol. The molar mass of Nitrogen is 14.007 grams/mol.

Question

a
38.312 grams/mol

b
148.248 grams/mol
c
90.631 grams/mol

d
100.929 grams/mo

Answer 1

a. 38.312 grams/mol

To calculate the molar mass of Magnesium Nitride (Mg3N2), you must multiply the atomic weight of Magnesium by 3 (since there are 3 Magnesium atoms in the compound) and the atomic weight of Nitrogen by 2 (since there are 2 Nitrogen atoms in the compound), and then add the two values together.

Molar mass of Magnesium Nitride (Mg3N2) = (3 x 24.305) + (2 x 14.007)
= 72.915 + 28.014
= 100.929 grams/mol

Therefore, the molar mass of Magnesium Nitride is 100.929 grams/mol.
