Answer:

less than 4.62 g

Explanation:

Sodium chloride contains 39% sodium by mass. Hence, 1 g of sodium chloride will contain:

39/100 x 1 = 0.39 g of sodium.

If 1 g of sodium chloride contains 0.39 g of sodium, then how many g of sodium chloride will contain the 1.8 g required sodium per day?

1 g sodium chloride = 0.39 g sodium

x g sodium chloride = 1.8 g sodium

x = 1.8 x 1/0.39 = 4.62 g of sodium chloride

Since the adult is supposed to consume less than 1.8 g of sodium per day, the mass of sodium that should be consume per day and still be within the FDA guidelines will be less than 4.62 g of sodium chloride.
