A block of copper of unknown mass has an initial temperature of 62.4 ∘C. The copper is immersed in a beaker containing 92.1 g of water at 22.6 ∘C. When the two substances reach thermal equilibrium, the final temperature is 25.0 ∘C. What is the mass of the copper block? Assume that Cs,H2O=4.18J/(g⋅∘C) and Cs,Cu=0.385J/(g⋅∘C). Express the mass to two significant figures and include the appropriate units.
