To express the weight in grams, we need to multiply it by the ratio that converts ounces to grams. The ratio that converts ounces (oz) to grams is: $\frac{28.125\ grams}{1\ ounce}$ So, 14 oz $\times$ $\frac{28.125\ grams}{1\ oz}$ = 14 $\times$ 28.125 grams = 393.75 grams Samir purchased a package of chips that weighted 393.75 grams.
