If 50.0 mL of ethanol (density=0.789g/mL)) initially at 7.0 ∘C is mixed with 50.0 mL of water (density=1.0g/mL) initially at 28.7 ∘C in an insulated beaker, and assuming that no heat is lost, what is the final temperature of the mixture?

Answer #1

heat lost by one system = heat gained by other system

q = ms\DeltaT

ethanol heat = water heat

(50*0.789)*2.46*(T2-7.0) = 50*4.184*(28.7 - T2)

T2 = 21.820C
