An insulated beaker with negligible mass contains liquid water with a mass of 0.350kg and a temperature of 76.3 degrees celsius.

How much ice at a temperature of −18.1 degrees celsius must be dropped into the water so that the final temperature of the system will be 35.5 degrees celsius?

Take the specific heat for liquid water to be 4190 J/kg.K, the specific heat for ice to be 2100 J/kg.K}, and the heat of fusion for water to be 334kJ/kg.

My final answer was 0.12kg, , but the feedback i received was "you are close". I can't seem to get the right answer for it. Please help.

Thanks
