How many atoms are in 163g of calcium?

Answer 1

To find the number of atoms in 163 grams of calcium, first determine the molar mass of calcium, which is approximately 40.08 g/mol. Next, calculate the number of moles in 163 grams by dividing 163 g by 40.08 g/mol, resulting in about 4.06 moles. Finally, multiply the number of moles by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol) to find that there are roughly (2.44 \times 10^{24}) atoms in 163 grams of calcium.
