The molar mass of magnesium (mg) is 24.30 g/mol. there are 6.02 1023 atoms in 1 mol. how many atoms are present in 48.60 g of mg? 3.32 10–24 atoms 1.96 10–21 atoms 1.20 1024 atoms 7.11 1026 atoms

1.2 x 10²⁴atoms

Explanation:

Given parameters:

Molar mass of Mg = 24.3g/mol

Mass of Mg = 48.6g

Number of atoms in 1 mole = 6.02 x 10²³ atoms

Solution

We know that

                1 mole contains  6.02 x 10²³ atoms

Now we have to find the number of moles that are in the given mass of the magnesium atom.

   Number of moles =

   Number of moles =   = 2mole

Now 2 moles of Mg will contain 2x 6.02 x 10²³ atoms = 1.2 x 10²⁴atoms

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
