Part A

A $33\mathrm{.}2g$ gold rod, initially at $20\mathrm{.}5C,$ is submerged into an unknown mass of water at $68\mathrm{.}4C,$ in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is $51\mathrm{.}7C.$ The specific heat capacity for gold is $0\mathrm{.}128\frac{J}{g*C}.$

What is the mass of the water?
