To find the number of moles in 14 grams of aluminum, you can use the formula:

Number of moles = mass of substance (in grams) / molar mass (in g/mol)

Given:
Mass of aluminum = 14 grams
Molar mass of aluminum = 27 g/mol

Substitute these values into the formula:

Number of moles = 14 g / 27 g/mol = 0.518 moles

So, there are approximately 0.518 moles in 14 grams of aluminum.
