4 g of NaOH are dissolved in `200 cm^3` of water. Find the molarity of the solution.

Explanation

To find the molarity of the solution when 4 g of NaOH is dissolved in 200 cm³ of water, we can follow these steps:

### Step 1: Identify the given data
- Mass of NaOH (solute) = 4 g
- Volume of solution = 200 cm³

### Step 2: Convert the volume from cm³ to liters
Since molarity is defined in terms of liters, we need to convert the volume:
