## Moles to Gram Calculator

Moles to gram calculator converts the given data value into grams and calculates the number of atoms present in the atom. It provides a step-by-step solution to the given value.

## What is a mole?

A mole is a unit of the amount of substance. Mole is Avogadro’s number of particles, which is exactly 6.02 × 1023. The unit mole is used because we can measure the amount of substance more easily than the other unit’s kilogram, million, billion, etc.

### Formula

To find the grams from the given number of moles, we have to use the formula

m = mol × w

where

• m is the mass of the substance which will be in grams.
• Mol is the number of moles of the substance.
• w is the weight of the substance.

## How to convert moles into grams?

Example 1:

Calculate the mass in grams of 2.7 mol of H2O.

Solution:

Step 1: Find the molecular mass of H2O.

H = 1.008

O = 16

Therefore, the molecular mass of H2O is

2(1.008) + 16 = 18.016

One mole of H2O weight is 18.016.

Step 2: By using the formula, we have

Now we have to find 2.7 mol of H2O.

=2.7 x 18.016

= 48.643

48.643 g of H2O.

Example 2:

Convert 5 moles of HCL to grams.

Step 1: Find the molecular mass of HCL.

One mole of HCL weight is 36.5.

Step 2: By using the formula, we have

Now we have to find 5 moles of H2O.

=5 x 36.5

= 109.5

109.5 g of HCL.
