If you combine 280.0 mL of water at 25.00 °C and 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.

Expert Solution

mass of water = volume * density

= 280*1 = 280g

mass of water = volume * density

= 140*1 = 140g

Q1 = Q2

mCt = mCt

280*4.18*(x-25) = 140*4.18*(95-x)

x = 48.34⁰C

final temperature = 48.34⁰ C
