    First, determine the number of moles of NaOH by multiplying the volume given with the molarity.

    n = (200 mL) (1 L/1000 mL) (0.150 mole/L)

    n = 0.03 moles

    Then, multiply the calculated number of moles above with the given molar weight.

    m = (0.03 moles) (40 g/mol)

    m = 1.2 g

    Answer: 1.2 grams of NaOH
