Best ResponseYou've already chosen the best response.0heat is transferred from the water is opposite to the heat transferred to the coffee. \[mC(T_{final}T_{initial})_{coffee}=mC(T_{final}T_{initial})_{water}\] heat capacity for coffee and water will essentially be the same so you're left with \[(100~g)(T40°C)=(50~g)(T100°C)\]
