Question

An insulated beaker with negligible mass contains liquid water with a mass of 0.235 kg and a temperature of 79.1 ∘C . How much ice at a temperature of -21.3 ∘C must be dropped into the water so that the final temperature of the system will be 29.0 ∘C ? Take the specific heat of liquid water to be 4190 J/kg⋅K , the specific heat of ice to be 2100 J/kg⋅K , and the heat of fusion for water to be 3.34×105 J/kg .

Answer #1

You can also convert it into grams in case you want.. In grams mass will be 98.6 gm
