Molar Mass Formula

Table of Contents

Each compound has mass and it is named as the molar mass in Chemistry. In this post, we will discuss the molar masses and steps to calculate the molar mass too. Substances occupy space and they have masses too. Substances are made up of molecules and they often need to measure in labs during experiments.

This is important that measurements should be accurate. But how can you measure something so accurately when it is limited in quantity? What is the right way to measure molecules? Mostly, chemists use a popular tool that is named as the analytical balance for measuring molar masses in grams.

Molar Mass Formula

\[\ Molar Mass =\frac{Grams}{Mole}\]

The other name for the molar mass is molecular weight and defined as the sum of the total mass in grams of all atoms that make up the mole for a specific molecule. The unit that is need to measure moles is grams per mole.

Steps to find the molar masses in Chemistry –

  • Calculate the atomic mass for each element available in the periodic table.
  • Count the number of atoms for each element.
  • Calculate the molar mass by plugin the values in the given formula.

Congratulation, you are done with a few simple steps! With careful calculation, scientists found that they can determine the total number of moles in a particular reaction. And one mole is a unit of measure that helps us to compare particles for a particular substance and its masses too. When you already know the number of moles required, the concept of molar mass can be used frequently.
