A copper calorimeter of mass ()g contains 380g of a liquid at 12degrees Celsius. A 20W heater is used for 3 minutes to raise the temperature of the liquid and calorimeter to 17 degrees Celsius. The calorimeter has a specific heat capacity of 400 J/K kg
a.Calculate the heat energy supplied to the calorimeter and the liquid inside it.
b.Calculate the heat supplied to the calorimeter.
c.Assuming no heat losses find the specific heat capacity of the liquid....

I just couldn't do part b and c. Is there enough information supplied in the question? Thanks
