if a sample of magnesium has a mass of 60 g, how many moles of magnesium does the sample contain

Sagot :

pyromorphite
1 mole of Mg ------------ 24,3g
x moles of Mg-------------60g
x = 2,47 moles of Mg

answer: 2,47 moles of magnesium

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
