WebStart with mL of NaOH, and use molarity to conver to moles. To find the moles of acid use stoichiometry. Remember, number of moles of acid is not the answer. You must find molar mass which is grams per mole. Titrations are really stoichiometry problems, but the formula of the acid is unknown. return to GenChem Home Page

WebMolar concentration allows us to convert between the volume of the solution and the moles (or mass) of the solute. Concept check: Bronze is an alloy that can be thought of as a … WebAug 9, 2024 · moles acid = moles base Recall that the molarity (M) of a solution is defined as the moles of the solute divided by the liters of solution (L). So the moles of solute are therefore equal to the molarity of a solution multiplied by the volume in liters. moles solute = M × L We can then set the moles of acid equal to the moles of base.
