Answer
There are approximately 3.58 moles of aluminum in 96.7 grams of Al.
Solution
The number of moles is given by the formula:
moles = mass / molar mass
For aluminum (Al), the molar mass is approximately 26.98 g/mol. So we calculate:
moles = 96.7 g / 26.98 g/mol ≈ 3.58 mol
Thus, there are approximately 3.58 moles of aluminum in 96.7 g of Al.

To find the number of moles of aluminum in 96.7 g of Al, we first need to know the molar mass of aluminum, which is approximately 26.98 g/mol. Using the formula: \[ \text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \] we calculate: \[ \text{moles} = \frac{96.7 \, \text{g}}{26.98 \, \text{g/mol}} \approx 3.58 \, \text{mol} \] So the correct answer is approximately 3.58 mol.
