When 1.0 g of solid naoh (triangle hsoln = –445.1 kj/mol) dissolves in 10 l of water, how much heat is released?

The heat being released is calculated by multiplying the amount of NaOH used for making the solution. We are given a delta H that is equal to -445.1 kJ / mol. This value is per mole NaOH. Calculation is as follows:

-445.1 kJ / mol NaOH (1.0 g NaOH ) ( 1 mol NaOH / 40 g NaOH ) = -11.1 kJ

Answer-ide.
