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.
