### Preparation of 1M solution

To prepare one liter of one molar solution of sodium hydroxide we need one mole of sodium hydroxide. you will need to dissolve 40 g of sodium hydroxide in one liter of water to get one liter of 1 molar solution.

## definition

### Molarity

Molarity(M) of a solution is defined as the number of moles of solute dissolved per litre of solution.
Molarity

## formula

### Molarity equation

If a solution having molarity and volume is diluted to volume so that the new molarity is then as the total number of moles will remain constant, we have
