for this question it says that 50g h20 at 20 degrees celsius is mixed with 65g of h20 at 50 degrees celsius and wants delta s and delta s total. In the solutions manual it uses q=-q and uses 75.3 for the specific heat. I was wondering where the number 75.3 comes from

That is the molar heat capacity. (4.18J/gm.Kelvin) x (18gm/mole) = 75.24J/mole.Kelvin
