Calculate the volume of carbon dioxide at NTP evolved by strong heating of 20g calcium carbonate.

Explanation

To calculate the volume of carbon dioxide (CO2) evolved from the strong heating of 20 grams of calcium carbonate (CaCO3), we can follow these steps:

### Step 1: Write the balanced chemical equation
The decomposition of calcium carbonate upon heating can be represented by the following balanced equation:
\[ \text{CaCO}_3 (s) \rightarrow \text{CaO} (s) + \text{CO}_2 (g) \]

### Step 2: Calculate the molar mass of calcium carbonate (CaCO3)
To find the molar mass, we need to sum the atomic masses of calcium (Ca), carbon (C), and oxygen (O):
