Question

Calculate the change in enthalpy produced by dissolving 14.3 g of NaOH in 65.0 g of water if the temperature increases 49.1°C and the specific heat of water is 4.18 J/g°C

I believe you multiply 4.18, 65.0, and 49.1. Am I correct

Answer 1

Yes and if that's all the question wants you're ok. However, most questions like this want kJ/mol or kJ/gram (in this case mol or g of NaOH).
