Question

What is the mass in grams of 4.85 x 1022 al atoms?

Answer 1

Based on the calculations, the mass of Aluminum in 4.85 × 10²² atoms is equal to 2.1762 grams.

How to calculate the mass of Aluminum?

In order to determine the mass of Aluminum, we would calculate the number of atoms in 1 mole of an Aluminum atom in accordance with Avogadro's constant.

1 mole of Aluminum atom = 6.02 × 10²³ molecules

X moles of Aluminum atom = 4.85 × 10²² molecules

Cross-multiplying, we have:

X = 4.85 × 10²²/6.02 × 10²³

X = 0.0806 moles.

Mass = Molar mass × Number of moles

Mass = 27 × 0.0806

Mass = 2.1762 grams.
