Question

Although units such as grams, kilograms and pounds (lb) are used in everyday life to measure the amount of substances, the unit “mole” (or mol) is common in chemistry–related fields. If 1 mol of silver weighs 108 g, how many kilograms of silver are there in a spoon made up of 3.09 mol of pure silver?

Answer 1

1 mole is 108 grams Ag so
3.09 moles must ber 3*108 = ? grams Ag.
Then Kg = grams/1000 = ?
By the way, so-called silver spoon aren't made of 100% Ag. Pure silver is too soft.

Answer 2

So it would be like 3(108)= 324
and then 324/1000= 0.324
