How many atoms are in a 0.84 lb sample of silver?

Answer 1

0.84 lb silver (454 grams/1 lb)(1 mole Ag/107.9 grams)(6.022 X 10^23/1 mole Ag)

= 2.1 X 10^24 atoms of silver

Answer 2

To find the number of atoms in a sample of silver, we first need to convert the mass from pounds to grams. Then we calculate the number of moles of silver using the molar mass of silver. Finally, we use Avogadro's number to convert moles to atoms. The answer would be approximately 2.0 x 10^23 atoms in a 0.84 lb sample of silver.
