Expert Answer
The number of moles of a species is calculated by expression (1), in which, n is the number of moles, m is the mass, and M is the molar mass of the species.
The molarity of a solution is the number of moles of solute present in one-liter solution as stated in equation (2), where, M is the molarity of solution, n is the number of moles, and V is the volume of solution in liters.
The enthalpy change of a reaction (ΔHrxn) is related to its specific heat in accordance with expression (3), in which, m is the mass of the metal, s is the specific heat, n is the number of moles of the limiting reactant, and ΔT is the change in temperature.
