Answer:50.4 moles of atoms are present in the sample.
Explanation:
Moles of carbon atom in propane = 14.1 moles of atom
Number carbon atoms [tex]14.1 mole\times 6.022\times 10^{23}=8.4\times 10^{24} atoms[/tex]
In one molecule of propane there are 3 carbon atoms and 8 hydrogen atoms
For 1 carbon atom there are = [tex]\frac{8}{3}[/tex] hydrogen atoms
Number of hydrogen atom for [tex]8.4\times 10^{24} atoms[/tex] of carbon :
[tex]=8.4\times 10^{24}\times \frac{8}{3} atoms=2.2\times 10^{25} atoms[/tex]
Total number of atoms =[tex]8.4\times 10^{24} atoms+2.2\times 10^{25} atoms [/tex]
[tex]=3.04\times 10^{25}[/tex] atoms
[tex]Moles=\frac{\text{Total number of atoms}}{6.022\times 10^{23}}[/tex]
[tex]Moles=\frac{3.04\times 10^{25}}{6.022\times 10^{23}}=50.4[/tex]
50.4 moles of atoms are present in the sample.
