The temperature of 300 g of water at `40^@`C is lowered to `0^@`C by adding ice to it. Find the mass of ice added if specific heat capacity of water is 4.2 J `g^(-1) K^(-1)` and specific latent heat of ice is 336 J `g^(-1)`

Explanation

To solve the problem, we need to find the mass of ice added to lower the temperature of 300 g of water from 40°C to 0°C. We will use the principle of conservation of energy, where the heat lost by the water will be equal to the heat gained by the ice.

### Step-by-Step Solution:

1. **Identify the heat lost by the water:**
The heat lost by the water can be calculated using the formula:
\[
Q_{\text{lost}} = m_{\text{water}} \cdot c_{\text{water}} \cdot \Delta T
