Answer:
There are 121.37 moles of methane(CH₄) in 7.31*10²⁵ molecules
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023 * 10²³ particles per mole. The Avogadro number applies to any substance.
Then a rule of three can be applied as follows: if 6,023*10²³ molecules are in 1 mole of CH₄, 7.31*10²⁵ molecules will be present in how many moles of the substance?
[tex]moles=\frac{7.31*10^{25}molecules*1mole }{6.023*10^{23}molecules }[/tex]
moles=121.37
There are 121.37 moles of methane(CH₄) in 7.31*10²⁵ molecules
