Answer

Answer:

1.30

Explanation:

Step1: Identify the conversion factor

The molar - mass of $MnO_2$ is $86.94\ g/mol$.

Step2: Calculate the number of moles

We use the formula $n=\frac{m}{M}$, where $n$ is the number of moles, $m$ is the mass, and $M$ is the molar mass. Given $m = 113\ g$ and $M=86.94\ g/mol$. So $n=\frac{113\ g}{86.94\ g/mol}\approx1.30\ mol$.
