How many moles are in 14.35 x 1022 molecules of H3PO4?
1 answer:
Answer:
0.24mole
Explanation:
Given parameters:
Number of molecules = 14.35 x 10²² molecules;
Unknown = number of moles of H₃PO₄
A mole of a substance is the quantity of matter that contains the avogadro's number of particles.
This number is given as 6.02 x 10²³ particles. The particles can be atoms, molecules, protons, electrons e.t.c
6.02 x 10²³ molecules is contained in 1 mole of any substance
14.35 x 10²² molecules will contain: = 0.24mole

Moles of electrons:
The moles of electrons that are transferred are 12F
A balanced equation:
2 moles of Aluminium metal react with excess copper(II) nitrate.
Given:
Moles of Aluminium = 2
As Aluminium goes from 0 to +3 oxidation state
And copper goes from +2 to 0
On balancing the number of electrons we get:
For 1 mole of Al is required.
Therefore for 2 moles of Al,
Total F mole of electrons
Where F= Faraday's constant= 96500 C
So, 12F moles of electrons are transferred.
