A pitcher contains 2.5 kg of water. 0.5 kg of ice cubes are added. What is the total mass of water after the ice melts?

The question asks for the total mass of water. To calculate this, we need:

• The initial mass of liquid water in the pitcher.
• The mass of the ice cubes added to the pitcher.

When ice melts, it undergoes a physical change from solid to liquid. The mass of the substance remains constant during this phase change. Therefore, the mass of the melted ice (liquid water) is equal to the initial mass of the ice cubes.

If the initial mass of water in the pitcher was $M_{\text{water}}$ and the mass of the ice cubes was $M_{\text{ice}}$, then the total mass of water after melting would be:

Since the values for $M_{\text{water}}$ and $M_{\text{ice}}$ are not given in the problem statement or the image, it is impossible to calculate the total mass of water and select one of the provided options.
