How many atoms are in 133g of calcium?
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.
How many calcium atoms are in 35.6 g of calcium?
To find the number of calcium atoms in 35.6 grams of calcium, you first need to calculate the number of moles of calcium. The molar mass of calcium (Ca) is approximately 40.08 g/mol. Thus, the number of moles in 35.6 g is 35.6 g ÷ 40.08 g/mol ≈ 0.887 moles. Since one mole contains Avogadro's number of atoms (approximately (6.022 \times 10^{23}) atoms/mole), the total number of calcium atoms is about (0.887 \times 6.022 \times 10^{23} \approx 5.34 \times 10^{23}) atoms.
