hybridization is defined as mixing up of the atomic orbital with nearly same energies according to linear combination of atomic orbitals. the orbitals formed are equal in energy and are called hybrid orbitals .
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
