Question

A chemist must calculate the amount of an element needed for a chemical reaction. The reaction requires 3.4 moles of silver. Help the chemist convert from moles to grams

Answer 1

3.4 moles of silver * 107.868 grams of silver/1 mole of silver = 370 grams of silver.

Step-by-step explanation:

According to the NYS Reference Table, one mole of silver equates to 107.868 grams. Therefore, if you want to convert from moles to grams, the mole unit should be on the bottom, since it is the unit being cancelled out. Above the mole unit should be the gram unit, since it is the unit you want to convert to. Once you do the math with significant figures, the solution turns out to be 370 grams of silver.
