Question

what is the molar mass of the covalent compound ncl3? ncl3 = ? $\frac{g}{mol}$

Explanation:

Step1: Identify molar - mass of elements

The molar mass of N is $14.01\ g/mol$ and of Cl is $35.45\ g/mol$.

Step2: Calculate molar mass of $NCl_3$

The formula for $NCl_3$ has 1 N atom and 3 Cl atoms. The molar mass $M$ of $NCl_3$ is $M = 1\times14.01\ g/mol+3\times35.45\ g/mol$.
$M=14.01\ g/mol + 106.35\ g/mol$.
$M = 120.36\ g/mol$.

Answer:

$120.36$
