How Do You Solve What Is The Mass Of 1.56 X 10^24 Atoms Mg? And Have The Answer In Grams?

With the help of definition of mole, we can find the mass of a substance by using number of atoms of the substance. Mole is equal to the ratio of number of atoms of a substance to Avogadro's number.

Mole = atoms/ Avogadro's number

Avogadro's number = 6.022 x 10²³ atoms

Given number of atoms = 1.56 x 10²⁴ atom

Moles = 1.56 x 10²⁴ atom / 6.022 x 10²³ atoms

Moles = 0.26 x 10

Moles = 2.6

Moles is the ratio of mass given to the molar mass. The molar mass of magnesium is 24 grams per mole.

Moles = mass/ molar mass

2.6 = mass / 24

mass = 2.6 x 24

Mass = 62.4 grams
