Insert the information in the form and the calculator will determine the grams to moles.

What is the grams to moles?

The mass of a substance in grams numerically equal to it's molecular weight.

How to calculate grams to moles?

To calculate grams to moles formula you should use the following formula:
n = m / M
where:
n = number of moles
m = mass
M = molar mass

example: The hydrogen peroxide have a molar mass of 37 g/mol calculate the number of moles that goes into 111g of it?

Using the grams to moles formula the answer will be:
n = m / M
n = 111 / 37
n = 3 mol

Why use grams to moles?

The grams to moles formula is used in order to know how many moles there is in a specific mass of the substance.
