How many atoms are in 12g of magnesium?

Answer 1

Amount of Mg = 12/24.3 = 0.494mol

1 mol of Mg contains 6.02 x 1023 Mg atoms (avogadro constant).

Number of atoms in 12g of Mg = 0.494 x 6.02 x 1023 = 2.97 x 1023

Answer 2

To determine the number of atoms in 12g of magnesium, you first need to convert the mass to moles using the molar mass of magnesium (24.31 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in that amount of magnesium. This will give you around 3.01 x 10^23 atoms.
