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

Explanation

To calculate the molarity of a `CaCO₃` (calcium carbonate) solution with a concentration of 200 ppm, follow these steps:

### Step 1: Understand the definition of ppm
Parts per million (ppm) means that there are 200 grams of calcium carbonate in 1,000,000 grams of solution (water in this case).

### Step 2: Convert grams of solution to liters
Since the density of water is approximately 1 g/mL, 1,000,000 grams of water is equivalent to 1,000,000 mL or 1,000 L.
