First calculate the moles of Calcium
Moles(Ca) = 169g/ 40 (Atomic Mass)
moles(Ca) = 4.225 moles.
Remember the Avogdro No. which is the number of ato,ms/molecules in one mole.
Hence 6.022 x 10^*23) = 1 mole.
We have 4.225 moles So multiplying
4.225 X 6.022 x 10^(23) = 2.54 x 10^(24) atoms)
To calculate the number of atoms in a sample of calcium, you need to first determine the moles of calcium in 169 g. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to find the number of atoms. The Atomic Mass of calcium is 40.08 g/mol, so 169 g of calcium is approximately 4.22 moles. Multiplying this by Avogadro's number gives approximately 2.54 x 10^24 atoms in 169 g of calcium.
