How many atom are in 141g of calcium?

Answer 1

To find out how many atoms are in 141 grams of calcium, you first need to determine the number of moles of calcium. The molar mass of calcium (Ca) is approximately 40.08 g/mol. Therefore, 141 g of calcium is about 3.51 moles (141 g / 40.08 g/mol). Since one mole contains Avogadro's number of atoms (approximately (6.02 \times 10^{23}) atoms), the total number of atoms in 141 g of calcium is about (2.11 \times 10^{24}) atoms (3.51 moles × (6.02 \times 10^{23}) atoms/mole).
