Question

Kelly's recipe calls for 11 ounces of chicken. Her scale only measures in grams. Which of the following shows the number of grams of chicken, with the correct significant digits, that Kelly needs to include in her recipe in order to have 11 ounces? (1 ounce = 28.3495 grams)
We can start by using dimensional analysis to convert 11 ounces to grams:

11 oz x (28.3495 g / 1 oz) = 311.845 g

To the correct significant digits, the answer is 312 g (since 11 ounces only has 2 significant digits). Therefore, Kelly needs 312 grams of chicken for her recipe.
