(Answered) A 35g copper cup contains 89g of drinking water the copper

Academics

A 35g copper cup contains 89g of drinking water. The copper cup is placed into a cooling device consisting of an insulated container which holds 85g of water equal in temperature to the drinking water. Ammonium chloride is added to the water in the cooling device (not the drinking water!) in order to cool the drinking water by 5.0°C? Theoretical value of molar enthalpy of ammonium chloride is 14.8 kJ/mol. The specific heat capacity of copper is 0.385(j)(g^1)(°C^-1)
