How many atoms are in 133g of calcium?

Answer 1

To find the number of atoms in 133 grams of calcium, first, calculate the number of moles using its molar mass, which is approximately 40.08 g/mol. Dividing 133 g by 40.08 g/mol gives about 3.31 moles of calcium. Then, multiply the number of moles by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol) to find the total number of atoms, which is about (2.00 \times 10^{24}) atoms of calcium.
