If you get stuck, click the links to use our chemical equation balance calculator to see the balanced result and the four easy steps to get there: Aluminium + Sodium Hydroxide + Water = Sodium Aluminate + Hydrogen Gas: Al + NaOH + H2O = NaAlO2 + H2. WebSo molarity is defined as moles of solute in moles divided by volume of solution in liters. Or as an equation M = n/V, where M is molarity, n is moles of solute, and V is volume. If you multiply the equation by volume you have a way to solve for number of moles, or MV = n.
