How many atoms of each type present in 143 g of washing soda `(Na_(2)CO_(3).10H_(2)O)` ?

Explanation

To find the number of atoms of each type present in 143 g of washing soda (Na₂CO₃·10H₂O), we will follow these steps:

### Step 1: Calculate the Molar Mass of Washing Soda
The formula for washing soda is Na₂CO₃·10H₂O. We need to calculate its molar mass.

- Sodium (Na): 2 atoms × 23 g/mol = 46 g/mol
- Carbon (C): 1 atom × 12 g/mol = 12 g/mol
- Oxygen (O) in Na₂CO₃: 3 atoms × 16 g/mol = 48 g/mol
