Respuesta :

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.
