    = 29.64 g NaNO3

    Explanation:

    Molarity is given by the formula;

    Molarity = Moles/Volume in liters

    Therefore;

    Number of moles = Molarity * Volume in liters

    = 1.55 M * 0.225 L

    = 0.34875 moles NaNO3

    Thus; 0.34875 moles of NaNO3 is needed equivalent to;

    = 0.34875 moles * 84.99 g/mol

    = 29.64 g
