Answer: To find molarity, we need to find moles of NaOH and liters of solution. The liters part is pretty easy (it’s told to us in the problem as 3.50 L) and the moles part just requires that we convert 87.4 grams of NaOH to moles (it’s 2.19 moles, using 40.0 g/mol as the molar mass of NaOH in the mole calculation).
