How many atoms are in 8.1 moles of oxygen? and how do you know?

4.88 x 10²⁴atoms

Explanation:

Given parameters:

Number of moles of oxygen = 8.1moles

Problem:

To find the number of atoms in 8.1moles of oxygen.

Method in solving the problem:

We know that a mole of a substance contains Avogadro’s number of particles which is 6.02 x 10²³

The particles can be molecules, atoms, etc.

Solution:

From the concept of mole,

Number of atoms =

number of moles x 6.02 x 10²³

Number of atoms = 8.1 x 6.02 x 10²³

Number of

atoms of oxygen = 48.8 x 10²³ atoms

= 4.88 x 10²⁴atoms

output?

explanation:

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
