How many moles of atoms are contained in 22.6 g of the Co?

Answer 1

1 mole Co = 58.933g Co (atomic weight in grams)

1 mole Co atoms = 6.022 x 1023 atoms Co

Convert grams Co to moles Co.

22.6g Co x (1 mole Co/58.933g) Co = 0.383 mole Co

Convert mole Co to atoms Co.

0.383 mole Co x (6.022 x 1023 atoms Co/1 mole Co) = 2.31 x 1023 atoms Co

Answer 2

The molar mass of cobalt (Co) is approximately 58.93 g/mol. To find the number of moles in 22.6 g of cobalt, you divide the mass by the molar mass: 22.6 g / 58.93 g/mol ≈ 0.383 moles of cobalt atoms.
