arrange the equation to calculate the molar mass, m. click the labpad if you would like more information.

Explanation:

Step1: Recall the molar - mass formula

The formula for the amount of substance $n=\frac{m}{M}$, where $n$ is the amount of substance in moles (mol), $m$ is the mass in grams (g), and $M$ is the molar mass in g/mol.

Step2: Rearrange the formula for $M$

Multiply both sides of the equation $n = \frac{m}{M}$ by $M$ to get $nM=m$. Then divide both sides by $n$ to isolate $M$. So, $M=\frac{m}{n}$.

Answer:

$M=\frac{m}{n}$
