Question

2. Convert 6.578 x 1023 atoms of magnesium to moles. 6.578 x 1023 atoms x mol atoms

Answer 1

Answer:

1.092 moles of Mg

Explanation:

Avogadro's number is a constant that define the number of particles (Such as atoms, molecules, electrons, ions) that you have in 1 mole. That means in 1 mole you have 6.022x10²³ of the particle in question.

If you have 6.578x10²³ atoms of Mg -and 1 mole of Mg contains 6.022x10²³ atoms of Mg-:

6.578x10²³ atoms of Mg × (1 mole Mg / 6.022x10²³ atoms of Mg) =

1.092 moles of Mg
