Explanation:
Number of oxygen molecules = 10 billion = [tex]10^9[/tex]
Number of hydrogen molecules = 10 billion = [tex]10^9[/tex]
Number of molecules of hydrogen peroxides = 10 billion = [tex]10^9[/tex]
Moles of oxygen gas :[tex]n_{o_2}[/tex]
[tex]\frac{10^9}{N_A}=\frac{10^9}{6.022\times 10^{23} mol^{-1}}=1.6605\times 10^{-15} mol[/tex]
Moles of hydrogen gas :[tex]n_{H_2}[/tex]
[tex]\frac{10^9}{N_A}=\frac{10^9}{6.022\times 10^{23}mol^{-1}}=1.6605\times 10^{-15} mol[/tex]
[tex]n_{O_2}=n_{H_2}[/tex]
Moles of hydrogen gas :[tex]n_{H_2O_2}[/tex]
[tex]\frac{10^9}{N_A}=\frac{10^9}{6.022\times 10^{23}mol^{-1}}}=1.6605\times 10^{-15} mol[/tex]
[tex]n_{O_2}=n_{H_2}-n_{H_2O_2}[/tex]
Number of moles in hydrogen gas, oxygen gas and hydrogen peroxide is same.
Total number of atoms in [tex]10^6[/tex] molecules of oxygen:
[tex]2\times 10^6[/tex] (2 atoms in 1 molecule)
Total number of atoms in [tex]10^6[/tex] molecules of hydroegn :
[tex]2\times 10^6[/tex](2 atoms in 1 molecule)
Total number of atoms in [tex]10^6[/tex] molecules of hydrogen peroxide:
[tex]4\times 10^6[/tex] (4 atoms in 1 molecule)
Number of oxygen atoms and number of hydrogen atoms are equal but individually they are not equal to number of atoms in hydrogen peroxide.
