Introduction

In chemistry, the molar mass of an element is a crucial concept that helps us understand the relationship between the mass of a substance and the number of moles it contains. The molar mass of aluminum (Al) is a specific value that we can use to calculate the number of moles of aluminum in a given mass. In this article, we will explore how to calculate the number of moles of aluminum in a sample of aluminum with a mass of 54.96 g.

Understanding Molar Mass

The molar mass of an element is the mass of one mole of that element. It is typically expressed in units of grams per mole (g/mol). The molar mass of aluminum is 26.98 g/mol, which means that one mole of aluminum has a mass of 26.98 grams.

Calculating Moles from Mass

To calculate the number of moles of aluminum in a given mass, we can use the following formula:

moles = mass / molar mass

In this case, we want to find the number of moles of aluminum in 54.96 g of aluminum. We can plug in the values we know into the formula:

moles = 54.96 g / 26.98 g/mol

Performing the Calculation

To perform the calculation, we can divide 54.96 g by 26.98 g/mol. This will give us the number of moles of aluminum in the sample.

moles = 54.96 g / 26.98 g/mol = 2.03 mol

Interpreting the Result

The result of the calculation tells us that there are 2.03 moles of aluminum in 54.96 g of aluminum. This means that the sample contains 2.03 moles of aluminum atoms.

Conclusion

In conclusion, the molar mass of aluminum is a crucial concept that helps us understand the relationship between the mass of a substance and the number of moles it contains. By using the formula moles = mass / molar mass, we can calculate the number of moles of aluminum in a given mass. In this article, we calculated the number of moles of aluminum in 54.96 g of aluminum and found that there are 2.03 moles of aluminum in the sample.
