You have 0.500-L of a 0.275-M solution of acetone (CzH60), initially at 37.0°C. You place a copper brick, initially at a temperature of 150.0°C, into the solution of acetone. The temperature of the acetone and copper brick at thermal equilibrium is 58.0°C. What was the mass of the copper brick? Assume the copper brick does not undergo a phase change over the course of the temperature change. Report your answer in units of g and to 3 significant figures.
