More calculations on temperature and thermal equilibrium

Here's another calculation problem on temperature and thermal equilibrium:

A $150 \text{ g}$ aluminum block at $150^\circ\text{C}$ is submerged into $400 \text{ g}$ of water at $25^\circ\text{C}$ in an insulated calorimeter. Determine the final equilibrium temperature of the mixture.

Given:

• Specific heat capacity of aluminum ($c_{Al}$) = $900 \text{ J/(kg}\cdot^\circ\text{C)}$
• Specific heat capacity of water ($c_w$) = $4186 \text{ J/(kg}\cdot^\circ\text{C)}$
