Thickness of strand hair = 50 μm
Diameter of an atom = 
Now, with the help of conversion factors, convert thickness in micrometer into meter i.e. 1 micrometer = 
So, thickness of strand hair =50 μm= 50 \times 10^{-6} m
Therefore,
number of atoms thick is a strand of hair = 
= 
Hence, number of atoms is thick is a strand of hair.
Two moles because one moles would be 6.02×10 23 atoms 2 moles would equal twice that number of atoms
Answer:
2.39 atm
Explanation:
- Use Gay-Lussac's law
- P2 = P1T2/T1
- Fill in with our values
- Hope this helped! Please let me know if you need further explanation.
Just find Ag and F on periodic table, find g/mol for each one and add them together
