If you have 320.0 mL of water at 25.00 °C and add 140.0 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 sum of the heats gained is zero (one looses heat, so is a negative heat gained).
Heatgaindcool+heatgainedhot=0
320c(Tf-25)+140c(tf-95)=0
do the algebra (notice c divides out), solve for Tf
