A solution is prepared by dissolving 1.0g of NaOH in water to get 250 ml of solution. Calculato its molarity.

Explanation

To calculate the molarity of the NaOH solution, we can follow these steps:

### Step 1: Calculate the number of moles of NaOH
First, we need to find out how many moles of NaOH are present in 1.0 g of NaOH. The molar mass of NaOH (sodium hydroxide) can be calculated as follows:

- Sodium (Na) = 23 g/mol
- Oxygen (O) = 16 g/mol
- Hydrogen (H) = 1 g/mol
