Question

Calculate the number of moles of C2H6 in 6.29×1023 molecules of C2H6.

Answer 1

1.05moles

Explanation:

Given parameters:

Number of molecules of C₂H₆ = 6.29 x 10²³molecules

Unknown:

Number of moles = ?

Solution:

The mole is the amount of substances that contains Avogadro's number of particles i.e 6.02 x 10²³

 To find the number of moles:

  number of moles = $\frac{number of particles}{Avogadro's number}$

  number of moles = $\frac{6.29 x 10^{23} }{6.02 x 10^{23} }$

  number of moles = 1.05moles
