A copper cube measuring 1.57cm on edge and an aluminum cube measuring 1.66cm on edge are both heated to 57.1oC and submerged in 100.0mL of water at 21.8oC. What is the final temperature of the water when equilibrium is reached? (Assume a density of 0.998 (g/mL) for water.) Im am really lost with how to even start this problem, please explain solution as much as possible.

A chemist dissolves 0.9 g of an unknown monoprotic (one acidic H) acid in water. She finds that 14.6 mL of 0.426 M NaOH are required to neutralize the acid.
used in high speed centrifuges to separate the parts of a biological cell. How many liters of 3.07 M sucrose contain 245 g of solute?
when 3.02g NH4Cl solid was dissolved in 20.05 ml water the temperature of the water dropped from 19.8 degrees celcius to 9.1 degrees celcius
Determine the new temperature and express your answer in degrees celsius,?
Tf will be negative and so you must use negative Kf values. Either way, the freezing point of the solution should be lower than that of the pure solvent. Assuming 100% dissociation, Find the freezing and boiling points of 1.85 m Na2SO4(aq).
