The Grams to Moles Calculator on your website is a useful tool that helps users convert a mass (in grams) of a substance into its corresponding amount in moles. It requires two inputs:

1. Mass (in grams): The weight of the substance in grams.

2. Weight of Substance (Molar Mass): The molar mass of the substance, which is typically expressed in grams per mole (g/mol).

The calculator uses the following formula to convert grams to moles:

1. Input the mass of the substance in grams.

2. Input the molar mass of the substance (its molecular weight in grams per mole).

3. The calculator will then compute the number of moles of the substance based on the inputs provided.

- If a user inputs a mass of 10 grams of water (H₂O) and the molar mass of water (18.015 g/mol), the calculator will compute the moles of water as:

This calculator is especially helpful in chemistry and other scientific fields where users need to convert the mass of a substance to moles to conduct reactions, prepare solutions, or understand molecular quantities. It simplifies the process of calculating moles when working with different substances with varying molar masses.
