When you have a chemistry (or any other type of!) problem involving converting from one type of units (here, the salt formula, and the #mol) to another type of unit (#atoms), you must work systematically to proceed from one end to the other. Web1 mol of NaOH has a mass of 40.00 g, so Moles of NaOH = 15.0g NaOH × 1 mol NaOH 40.00g NaOH = 0.375 mol NaOH Litres of solution = 225mL soln × 1 L soln 1000mL soln = 0.225 L soln Molarity = moles of solute litres of solution = 0.375 mol 0.225 L = 1.67 mol/L Some students prefer to use a "molarity triangle". It summarizes the molarity formulas as
