Answer : The moles of magnesium will be, 2.5 moles
Explanation : Given,
Mass of magnesium = 60 g
Molar mass of magnesium = 24 g/mole
Formula used :
Moles of M g = Molar mass of M g Mass of M g ​
Now put all the given values in this formula, we get the moles of magnesium.
Moles of M g = 24 g / m o l e 60 g ​ = 2.5 m o l e
Therefore, the moles of magnesium will be, 2.5 moles

A 60 g sample of magnesium contains 2.5 moles of magnesium. This is calculated using the molar mass of magnesium, which is 24 g/mol. By dividing the mass of the magnesium by its molar mass, we find the number of moles.
