Answer to Question #286016 in Physical Chemistry for Ruru

Question

50ml of water at 20°C was mixed with 100ml of water at 90°C.The density of water is about 1g/ml. Determine the final temperature after mixing the two samples of water?

Answer 1

T(final) = (m1_T1 + m2_T2) / (m1 + m2)

(50×20+100×90)/(100+50)

1000+9000/150

= 10000/150=66.67°C
