How many silver atoms are there in 3.78 of silver?

Answer 1

2.11 x 10^22

This is how you figure it out:

3.78g divided by 107.87(the Atomic Mass of silver). Then you multiply the number you get by 6.022x10^23 (Avogadros number). And that's your answer.

Answer 2

To find the number of silver atoms in 3.78g of silver, first calculate the molar mass of silver (Ag) which is 107.87 g/mol. Next, convert 3.78g of silver to moles by dividing by the molar mass. Finally, use Avogadro's number (6.022 x 10^23) to find the number of atoms, which will be approximately 6.61 x 10^22 atoms.
