Hint: The molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of $1$ mole of the substance or $6.022 \times {10^{23}}$ particles, expressed in grams.
Complete answer:
To calculate the molar mass for $Mn{O_2}$we must follow the following steps:
$ - $ Use the chemical formula to determine the number of each type of atom present in the compound.
$ - $Multiply the atomic weight of each element by the number of atoms of that element present in the compound.
$ - $Add it all together and put units of $grammo{l^{ - 1}}$ after the number.
The equivalent weight of $Mn{O_2}$ is the same as its molecular weight. The molar mass and molecular weight of $Mn{O_2}$ is $86.937$.
Additional information:
Manganese dioxide is the inorganic compound with the formula $Mn{O_2}$. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for $Mn{O_2}$ is for dry cell batteries, such as the alkaline battery and the zinc carbon battery. $Mn{O_2}$is also used as a pigment and as a precursor to other manganese compounds, such as $KMn{O_4}$
Note:
A specialized use of manganese dioxide is as an oxidant in organic synthesis. The effectiveness of the reagent depends on the method of preparation, a problem that is typical for other heterogeneous reagents where surface area, among other variables, is a significant factor.
