How many moles are in 3.0x10 to the 22 power atoms of magnesium

0.0498 moles

Explanation:

We are given;

Number of atoms of Magnesium 3.0 * 10^22 atoms

We are required to calculate the number of moles of Magnesium;

We need to know that 1 mole of an element contains 6.022 * 10^23 atoms. Thus; 1 mole of Mg = 6.022 * 10^23 atoms Therefore, to get the number of moles of Mg we divide the number of atoms given by the number of atoms in 1 mole.

Moles = 3.0 * 10^22 atoms : 6.022 * 10^23 atoms/mol

= 0.0498 moles

Hence, the number of moles in 3.0 * 10^22 atoms is 0.0498 moles
