Answer:

The answer to your question is: 3.82 moles of Calcium

Explanation:

Data

8.461 x 10²⁴ atoms Ca

                                   1 mol of Ca -------------------- 6.023 x 10²³ atoms

                                   x                  ------------------- 8.461 x 10²⁴ atoms

                                  x = (8.461 x 10²⁴ x 1) / 6.023 x 10²³

                                 x = 3.82 moles of Calcium

8.461 x 10²⁴ atoms of calcium is equal to 14.1 moles of calcium.

CALCULATE MOLES FROM NUMBER OF ATOMS:

  • The number of moles contained in a substance can be calculated by dividing the number of atoms in that substance by Avogadro's number:

no. of moles = no. of atoms ÷ 6.02 × 10²³

no. of moles = 8.461 x 10²⁴ ÷ 6.02 × 10²³

no. of moles = 8.461/6.02 × 10²⁴-²³

no. of moles = 1.41 × 10¹

no. of moles = 14.1 moles.

  • Hence, 8.461 x 10²⁴ atoms of calcium is equal to 14.1 moles of calcium.
