How many mole of magnesium atoms are present in 0.50g of manesium (mg=24)

What is .50g/24 ?

0.02mole

To calculate the number of moles of magnesium atoms present in 0.50g of magnesium, you need to use the formula:

Number of Moles = Mass / Molar Mass

First, let's determine the molar mass of magnesium (Mg), which is given as 24 g/mol.

Now we can plug in the values into the equation:

Number of Moles = 0.50g / 24 g/mol

Divide 0.50g by 24 g/mol:

Number of Moles = 0.0208 mol

Therefore, there are approximately 0.0208 moles of magnesium atoms in 0.50g of magnesium.
