Answer:

.5 moles of calcium

Step-by-step explanation:

We want to find the number of moles in 3.01 x 10^23 atoms of calcium

To convert atoms to moles, we simply divide the given number of atoms by Avogadro's number , 6.022 x 10^23

Given number of atoms : 3.01 x 10^23

Number of moles : 3.01 x 10^23 / 6.022 x 10^23 = .5 moles of calcium ( rounded )
