Calculate the number of molecules in each of the following :
11 g of `CO_(2)`
Given atomic masses : P = 31 u, C = 12 u, O = 16 u

Explanation

To calculate the number of molecules in 11 g of CO₂, we can follow these steps:

### Step 1: Determine the molar mass of CO₂
The molar mass of a compound is calculated by summing the atomic masses of its constituent elements.

- The atomic mass of Carbon (C) = 12 u
- The atomic mass of Oxygen (O) = 16 u
