Cierra needs 3000 mg of zinc for a science experiment which expression can be used to determine how many grams of zinc she needs

Answer 1

To determine how many grams of zinc Cierra needs, the following expression can be used:

3000 mg of zinc * (1 g / 1000 mg) = X grams

Where X represents the number of grams of zinc needed for the science experiment. This calculation converts the 3000 mg of zinc into grams by using the conversion factor of 1 g = 1000 mg.
