A piece оf leаd with аn unknоwn mаss has an initial temperature оf 88.0°C. The lead is immersed in a beaker containing a 141.3 g of water at 23.5°C. When they reach thermal equilibrium, the final temperature is 25.2°C. What is the mass of the piece of lead, g? (Specific heat of Pb = 0.128 J/g·°C; Specific heat of H2O = 4.184 J/g·°C)
