cold water
mass of calimeter+ water: 68.66g
mass of calimeter: 19.19g
mass of water: 49.47g
final temperature of water: 39.1C
initial temperature of water: 25.5C
delta(T) of water: 13.6C
hot water
mass of calimeter+ water: 79.55g
mass of calimeter: 20.61g
mass of water: 58.94g
final temperature of water: 39.1C
initial temperature of water: 52.2C
delta(T) of water: 13.1C
calulate the qhotwater (specific heat of water 4.18J g^1 C^1)
calculate the qcoldwater
can someone please explain to me how this question is done? thanks =]

q for hot water = mass H2O x specific heat H2O x (TfinalTinitial).
q for cold water = mass H2O x specific heat H2O x (TfinalTinitial).
