Calculate molarity of `CaCO_(3)`(aq.) solution which has concentration of `CaCO_(3)=200`ppm.

Explanation

To calculate the molarity of a \( \text{CaCO}_3 \) (calcium carbonate) solution with a concentration of 200 ppm, we can follow these steps:

### Step 1: Understand the definition of ppm
- PPM (parts per million) means that there are 200 grams of \( \text{CaCO}_3 \) in 1,000,000 grams of solution (which is approximately equivalent to 1,000,000 mL of water, since the density of water is about 1 g/mL).

### Step 2: Convert ppm to grams per liter
- Since 200 ppm means 200 grams of \( \text{CaCO}_3 \) in 1,000,000 mL of solution, we can convert this to grams per liter (g/L):
