Question

Number of Ag atoms in .240 mol

Answer 1

1.445 x 10²³ atoms.

Step-by-step explanation:

• It is known that 1.0 mole of any element contains Avogadro's no. (6.022 x 10²³) of atoms.

Using cross multiplication:

1 mol of Ag contains → 6.022 x 10²³ atoms.

∴ 0.24 mol of Ag contains → ??? atoms.

∴ The no. of Ag atoms in 0.24 mol = (0.24 mol)(6.022 x 10²³ atoms)/(1 mol) = 1.445 x 10²³ atoms.
