How many moles are in 4.3 x 1022 molecules of H3PO4?
Answers
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.
