To find the mass of NaOH in the solution, first calculate the number of moles of NaOH using the molarity formula (moles = molarity × volume in liters). For a 0.300 M solution and a volume of 150.0 mL (or 0.150 L), the moles of NaOH are 0.300 M × 0.150 L = 0.045 moles. Then, multiply the moles by the molar mass of NaOH (40.0 g/mol) to get the mass: 0.045 moles × 40.0 g/mol = 1.80 g.
