How many atoms are in 163 g of calcium?

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number of particles.

To calculate the number of moles, we use the equation:

1 mole of calcium contains =

Thus 4.075 moles of calcium contains =

Thus there are in 163 g of calcium.
