Using the heat of fusion of acetic acid, 192 J/g, calculate the grams of acetic acid that will freeze at its freezing point if 5.10 kJ is removed.
Homework Answers
heat of fusion of acetic acid = 192 J/g,
Amound of heat removed = 5.10 kJ = 5100 Joules
Q = m x ht of fusion
Substitute the values in the above equation and find the mass of acetic acid (m)
5100 Joules = m x 192 J/g
m = 5100 Joules / 192 J/g = 26.5625 gm
Hence 25.5625 gm of acetic acid can be frozen by taking 5100 joules of heat.
