First, look up the Atomic Mass of calcium: 40.08 grams per mole
143 grams, divided by 40.08 grams per mole, results in 3.57 moles.
Since you specifically asked for the number of ATOMS, multiply by Avogadro's number, 6.02 x 10-to-the-23rd-power atoms per mole.
Final answer: 2.15 x 10-to-the-24th power atoms.
