Answer
Samir purchased a package of chips that weighted 393.75 grams.
Work Step by Step
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
