`1.7 g` of silver nitrate dissolved in `100 g` of water is taken. `0.585 g` of sodium chloride dissolved in `100 g` of water is added to it an chemical reaction occurs. `1.435 g` of silver chloride and `0.85 g` of sodium nitrate are formed. Justify that the data obey law of conservation of mass.

Explanation

To justify that the data obeys the law of conservation of mass, we will calculate the total mass before and after the chemical reaction and show that they are equal.

### Step 1: Calculate the total mass before the reaction
1. **Mass of Silver Nitrate (AgNO₃)**: 1.7 g
2. **Mass of Sodium Chloride (NaCl)**: 0.585 g
3. **Mass of Water (H₂O)**: 100 g + 100 g = 200 g (since we have 100 g of water for each solution)

**Total mass before the reaction**:
