A silver block, initially at 55.1∘C, is submerged into 100.0 g of water at 25.2∘C in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 27.9∘C. The specific heat capacities for water and silver are Cs,water=4.18J/(g⋅∘C) and Cs,silver=0.235J/(g⋅∘C).

Question

Part A
What is the mass of the silver block?
Express your answer to two significant figures and include the appropriate units.

Answer 1

(55.1 - 27.9) * 0.235 * m = (27.9 - 25.2) * 4.18 * 100.0

m is in grams
