Answer : The moles of tungsten are, 79.707 moles
Explanation : Given,
Number of atoms of tungsten = [tex]4.8\times 10^{25}[/tex]
As we know that,
1 mole of substance contains [tex]6.022\times 10^{23}[/tex] number of atoms.
or we can say that,
As, [tex]6.022\times 10^{23}[/tex] atom of tungsten present in 1 mole of tungsten
So, [tex]4.8\times 10^{25}[/tex] atom of tungsten present in [tex]\frac{4.8\times 10^{25}}{6.022\times 10^{23}}=79.707[/tex] mole of tungsten
Therefore, the moles of tungsten are, 79.707 moles
A mole is the amount of substance that contains as many elementary chemical units as present in 12 gram of Carbon 12. 79.707 mole of Tungsten contains [tex]\bold{ 4.8 \times 10^2^5}[/tex]
Mole:
It is the quantity of substance that contains as many elementary chemical units as present in 12 gram of Carbon 12.
[tex]\bold{1mole = 6.02 \times 10^2^3}[/tex]
Number of mole [tex]\bold{ = \frac{ 4.8 \times 10^2^5 }{6.02\times 10^2^3} }[/tex]
Number of moles = 79.707 mole
Hence, we can conclude that 79.707 mole of Tungsten contains [tex]\bold{ 4.8 \times 10^2^5}[/tex] atoms.
