An aluminum calorimeter of mass 400g contains 200g of water at a temperature of 18celcius.When a block of nickel at a temperature of 80celcius is dropped into the water£¬the final temperature of the mixture becomes 28celcius. Find the mass of the nickel.

Answer 1

The sum of heats gained is zero. Heat gained=mcDeltaT

400*calum*(28-18)+200*cwater*(28-18)+MassNi*Cni*(28-80)=0

solve for MassNi
