Answer

Brief Explanations:

To convert grams of a substance to moles, we need its molar mass. The periodic table provides atomic masses which are used to calculate molar mass of compounds like water ($H_2O$). A scale measures mass, a thermometer measures temperature, and a spectrophotometer measures light - absorbance.

Answer:

C. the periodic table
