Answer : The moles of glucose in the sample is [tex]5.05\times 10^4moles[/tex].
Solution : Given,
Total number of atoms in a sample of glucose = [tex]7.3\times 10^{29}atoms[/tex]
As per the question, 1 mole of glucose molecule contains 6 atom of carbon, 12 atom of hydrogen and 6 atom of oxygen.
Total number of atoms in glucose = 6 + 12 + 6 = 24 atoms
As we know,
1 mole contains [tex]6.022\times 10^{23}atoms[/tex]
and 1 mole of glucose contains [tex]6.022\times 10^{23}\times 24 atoms[/tex]
or we can say that,
[tex]6.022\times 10^{23}\times 24 atoms[/tex] will make 1 mole of glucose molecule
[tex]7.3\times 10^{29}atoms[/tex] will make [tex]\frac{1mole}{6.022\times 10^{23}\times 24 atoms}\times 7.3\times 10^{29}atoms=5.05\times 10^4moles[/tex] of glucose molecule
Therefore, the moles of glucose in the sample is [tex]5.05\times 10^4moles[/tex].
