    As per the law of constant composition, a given sample will always contain the same number of elements that combine in the same mass proportion.

    Therefore if a sample of 13.97 g of NaBr contains 22.39 % of Na by mass then, a sample of 5.75 g of NaBr would also contain 22.39% Na by mass

    Hence:

    Mass of Na = 5.75 g * 22.39/100 = 1.287 g

    5.75 g of NaBr would contain 1.29 g of Na
