Given:

4.3 x 10^22 molecules of H3PO4.

To find:

Number of moles of H3PO4.

Solution:

We know that,

avogardo's number= 6.023 * 10^23.

number of moles = (Number of molecules)/( Avogadro number)

                             = (4.3×10^22)/(6.023×10^23)

                             = 0.73 × 10^-1

                            = 0.073 moles.

Answer:

There are 0.073 moles in 4.3 x 10²²molecules H₃PO₄.This calculation can be computed easily by the following method:

Given:

There are 4.3 x 10²² molecules of H3PO4, which means there are 4.3 x 10²² atoms of H₃PO₄. This is because each molecule of H₃PO₄ is made up of 3 atoms of hydrogen, 1 atom of phosphorus, and 4 atoms of oxygen.

To find:

To calculate the number of moles of H₃PO₄

Solution:

Therefore, we can calculate the number of moles of H₃PO₄ by dividing the number of atoms of H₃PO₄ (4.3 x 10²²) by Avogadro's number (6.022 x 10²²).

No of moles of H3PO4 = (4.3 x 10²²)/(6.022 x 10²³)

This gives us a result of 0.73 x 10⁻¹ moles of H₃PO₄.

In summary, there are 0.73x 10⁻¹ moles or 0.073 mol of H3PO4 in 4.3 x 10²² molecules of H₃PO₄.
