Question

An 11.98-gram sample of zinc metal is placed in a hot water bath and warmed to 78.4°C. It is then removed and placed into a Styrofoam cup containing 50.0 mL of room temperature water (T=27.0°C; density = 1.00 g/mL). The water warms to a temperature of 28.1°C. Determine the specific heat capacity of the zinc

Answer 1

Sum of the heats gained is zero in the cup.
Heatgained by water+heatgained by zinc=0

50cw*(28.1-27)+11.98Czinc*(28.1-78.4)=0
solve for Czinc
