How many moles of silver atoms are there in 1.8 x 1020 atoms of silver?
To calculate the number of moles of silver atoms in 1.8 x 10^20 atoms of silver, first we need to find the molar mass of silver.
The molar mass of silver (Ag) is 107.87 g/mol.
Next, we need to convert the number of atoms given into moles using Avogadro's number (6.022 x 10^23 atoms/mol).
1.8 x 10^20 atoms of silver * 1 mol / 6.022 x 10^23 atoms = 2.99 x 10^-4 moles of silver atoms
Therefore, there are 2.99 x 10^-4 moles of silver atoms in 1.8 x 10^20 atoms of silver.
