Table salt contains 39.33 g of sodium per 100 g of salt. The U.S. Food and Drug Administration (FDA) recommends that adults consume less than 2.40 g of sodium per day. A particular snack mix contains 1.21 g of salt per 100 g of the mix.

What mass of the snack mix can you consume and still be within the FDA limit?
