The number of atom in 0.75 mol will be 4.5165 × [tex]10^{23}[/tex] atom.
An atom would be a single-celled piece of matter that identifies a chemical element. An atom is made up of a core nucleus surrounded by one or maybe more electrons.
It is given that,
Number of mol = 0.75
1 mol = 6.022 × [tex]10^{23}[/tex] atom
So, 0.75 mol = 0.75 × 6.022 × [tex]10^{23}[/tex] atom
= 4.5165 × [tex]10^{23}[/tex] atom.
Therefore, the number of atom in 0.75 mol will be 4.5165 × [tex]10^{23}[/tex] atom.
