Question

what is the molar mass of the covalent compound n2o? n2o = ? $\frac{g}{mol}$

Explanation:

Step1: Determine nitrogen's contribution

The atomic mass of N is 14.01 g/mol and there are 2 N atoms in N₂O. So the mass contribution of N is $2\times14.01$ g/mol.
$2\times14.01 = 28.02$ g/mol

Step2: Determine oxygen's contribution

The atomic mass of O is 16.00 g/mol and there is 1 O atom in N₂O. So the mass contribution of O is 16.00 g/mol.

Step3: Calculate molar - mass of N₂O

Add the mass contributions of N and O.
$28.02+16.00 = 44.02$ g/mol

Answer:

44.02 g/mol
