If you combine 270.0 mL of water at 25.00 °C and 120.0 mL of water at 95.00 °C, what is the final temperature of the mixture? Use 1.00 g/mL as the density of water.

The density of water is of no interest. The problem is worked without knowing the density by treating the problem as a weighted average:
((270.0 mL x 25.00 °C) + (120.0 mL x 95.00 °C)) / (270.0 mL + 120.0 mL) = 46.54 °C
