An insulated beaker with negligible mass contains liquid water with a mass of 0.210 and a temperature of 64. How much ice at a temperature of -11.

An insulated beaker with negligible mass contains liquid water with a mass of 0.210 and a temperature of 64.6.How much ice at a temperature of -11.7 must be dropped into the water so that the final temperature of the system will be 25.0?Take the specific heat of liquid water to be 4190 , the specific heat of ice to be 2100 , and the heat of fusion for water to be
