This is the problem, What amount of energy, in Joules, is lost by 128.0 grams of water at 67.5 when liquid nitrogen is added to the water cooling it to 24.0? Enter your answer in scientific notation without units. The specific heat of water is 4.184 J/Kg.
Now if i'm not mistaken the correct answer is in the form of
(.128)*(4.184)*(24-67.5)
which gives 23.297, for some reason my answer is wrong
