One mole is equal to [tex]6.02\times 10^{23}[/tex] atoms.
We will use unitary method that says unitary method is a process used to solve a situation by finding the value of a single unit, (by dividing) and then finding the necessary value by multiplying the single unit value.
Now we need to know how many moles are there in [tex]8 \times 10^{23}[/tex]
[tex]6.02\times 10^{23}[/tex] atoms make 1 mole
1 atom makes [tex]\frac{1}{6.02 \times 10^{23}}[/tex] mole
Therefore,
[tex]8.0\times 10^{23}[/tex] atoms will make
[tex]\frac{8 \times 10^{23}}{6.02\times 10^{23}} =1.328[/tex] moles.
Therefore, [tex]8 \times 10^{23}[/tex] atoms make 1.328 moles.
Solution:-[tex]\text{Given that one mole consist}\ N_{o}=6.022\times10^{23}atoms\\\text{[which is Avagadro Number]}\\\text{and given number of atoms=N}\ =8\times10^{23}atoms\\\text{Moles in N}=\frac{N}{\ N_{o}}=\frac{8\times10^{23}atoms}{6.022\times10^{23}atoms}\\\text{so we cancel}\ 10^{23}\text{atoms from both the numerator and denominater}\\=\frac{8}{6.022}\\\text{Now by solving it ,we get}\\m=1.3284[/tex]
Here, Avogadro's number is the number of units in one mole of any substance (defined as its molecular weight in grams), equal to [tex]N_{o}=6.022\times10^{23}atoms[/tex]
One mole is the number of atoms in naturally-occurring isotope of the element carbon. This number is equal to approximately [tex]N_{o}=6.022\times10^{23}atoms[/tex]
