How many moles of h3po4 are there in 658 grams of h3po4?

Answer : There are 6.71 moles of H₃PO₄.

Explanation:

The mole of a substance is calculated as

Let us find the molar mass of H₃PO₄.

Molar mass of H₃PO₄ = 3 x atomic mass of H + atomic mass of P + 4x atomic mass of O

From the periodic table, we have

Atomic mass of H = 1.008 g/mol

Atomic mass of P = 30.973 g/mol

Atomic mass of O = 15.999 g/mol

Molar mass of H₃PO₄ =

Molar mass of H₃PO₄ is 97.993 g/mol

The mass of H₃PO₄ is given as 658 g.

The moles can be calculated as,

There are 6.71 mol in the given amount of H₃PO₄

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

it should be all of them because it asks if you included all of those in your answer
