    Answer: - 3333 g of solution.

    Some of the question part is missing here. It would be like, "Determine the mass in grams of each NaCl solution that contains 1.5 g of NaCl.

    (i) 0.045% NaCl by mass

    Solution: - 0.045% NaCl by mass means 0.045 g of NaCl are present in 100 g of solution. 1.5 g of NaCl would be present in how many grams of solution?

    We could solve this using proportions ...

    (0.045/100) = (1.5/X)

    0.045 (X) = 1.5 (100)

    0.045X = 150

    X = 150/0.045 = 3333

    So, 1.5 g of NaCl is present in 3333 g of solution.
