0 Comment.

2 Answer

  • Molar mass of aluminum ( Al ) = 26.98 g/mol

    n = m / M

    n = 0.50  / 26.98 

    n = 0.01853 moles

    hope this helps!

  • Answer: The number of moles of 0.50 g Aluminium is 0.0185 moles.

    Explanation:

    To calculate the number of moles, we use the formula:

    [tex]Moles=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]

    In the given question:

    Given mass of Aluminium = 0.50 g

    Molar mass of Aluminium = 27 g/mol

    Putting values in above equation, we get:

    [tex]\text{Moles of Aluminium}=\frac{0.50g}{27g/mol}=0.0185moles[/tex]

    Hence, the number of moles of 0.50 g of Aluminium is 0.0185 moles.
