If 50.0grams of copper initially at 145.0 C is put into 150.0mL of water initially at 25.00C, then what will the final temperature of the mixture be? assume that all of the heat lost by the hot copper is absorbed by the cold water.

first convert the volume into Liter by dividing it by 1000. convert 20 grams of CaBr2 by its molar mass into moles. (20 grams CaBr2)(1mol of CaBr2/199.89 g) = 0.100 mole CaBr2 Molarity is moles/ liters = 0.100 moles/0.5L = 0.200M
