How to Calculate the Mass of Oxygen Atoms in Grams

How can we determine the mass in grams from 6.3 × 10¹⁰⁰ atoms of oxygen?

Is there a specific formula or process to convert the number of oxygen atoms into grams?

Answer:

In order to determine the mass in grams from 6.3 × 10¹⁰⁰ atoms of oxygen, we need to follow a specific calculation method.

To determine the mass in grams from a given number of atoms of a specific element, such as oxygen, we need to utilize Avogadro's number and the molar mass of the element. In this case, oxygen has an atomic mass of approximately 16.00 g/mol.

The first step is to convert the given number of atoms (6.3 × 10¹⁰⁰) into moles. This can be done by dividing the number of atoms by Avogadro's number, which is approximately 6.022 × 10²³ atoms/mol. The formula for this calculation is:

Moles of O = 6.3 × 10¹⁰⁰ atoms / 6.022 × 10²³ atoms/mol

Once we have determined the number of moles of oxygen, we can then calculate the mass in grams by multiplying the number of moles by the molar mass of oxygen:

Mass = Moles of O x Molar mass of O

By following these steps, we can accurately determine the mass in grams from a given number of oxygen atoms. Understanding the relationship between atoms, moles, and grams is essential in chemistry and allows us to make precise calculations.
