I had to do an experiment to calculate the enthalpy of solution of Epsom salts. I'm stuck on how to calculate the amount of the reactant in moles. Here's some preliminary data:
37.58 g of Epsom salts in the solution
Molar mass of solution: 246.48 g/mol
I'm not sure what to do next.
mols = grams/molar mass.
