Final answer:
In 4.512 moles of silver (Ag), there are 486.8 grams of silver. The molar mass of silver is used to convert moles into grams.
Step-by-step explanation:
The subject of the question is related to the concept of moles in chemistry. To answer the question, we first need to know the molar mass of silver (Ag), which is 107.87 grams per mole. This means that one mole of silver weighs 107.87 grams.
To find out how many grams of silver are in 4.512 moles, we simply multiply the number of moles by the molar mass of silver: 4.512 moles * 107.87 g/mole = 486.8 grams Ag. Therefore, the correct answer is (A) 486.8 grams Ag.
