if a sample of magnesium has a mass of 60 g, how many moles of magnesium does the sample contain
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 :
[tex]\text{Moles of }Mg=\frac{\text{Mass of }Mg}{\text{Molar mass of }Mg}[/tex]
Now put all the given values in this formula, we get the moles of magnesium.
[tex]\text{Moles of }Mg=\frac{60g}{24g/mole}=2.5mole[/tex]
Therefore, the moles of magnesium will be, 2.5 moles
