To find the number of atoms in 78 grams of magnesium (Mg), first determine the molar mass of magnesium, which is approximately 24.31 g/mol. Then, calculate the number of moles in 78 grams by dividing 78 g by 24.31 g/mol, resulting in about 3.21 moles of Mg. Finally, multiply the number of moles by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol) to find that there are about (1.93 \times 10^{24}) atoms in 78 grams of magnesium.

What is the fractional abundence for 24Mg?
The fractional abundance of (^{24}\text{Mg}) is the ratio of the number of (^{24}\text{Mg}) atoms to the total number of magnesium atoms in a sample. Typically, (^{24}\text{Mg}) constitutes about 79% of naturally occurring magnesium isotopes, with the remaining isotopes being (^{25}\text{Mg}) and (^{26}\text{Mg}). Therefore, the fractional abundance of (^{24}\text{Mg}) can be expressed as approximately 0.79.
