How many atoms of Ca are in 4.7 moles of calcium?

There are atoms in 4.7 moles of calcium.

Explanation:

According to Avogardo's number for every 1 mole of a substance there will be atoms.

For the given Ca atom there are 4.7 moles. Hence the number of atoms present in 4.7 moles will be calculated as follows.

         Moles present = atoms

                                  = atoms

Thus, we can conclude that there are atoms in 4.7 moles of calcium.
