Answer

Explanation:

Step1: Identify conversion factor

We know that 1 mol of $NO_2$ has a mass of 46.01 g.

Step2: Calculate moles

Use the formula $n=\frac{m}{M}$, where $n$ is the number of moles, $m$ is the mass, and $M$ is the molar - mass. Here, $m = 118$ g and $M=46.01$ g/mol. So $n=\frac{118}{46.01}$. $n=\frac{118}{46.01}\approx2.56$ mol

Answer:

2.56
