1 mole ----------------- 6.02 x 10²³ molecules
10.0 moles ----------- ( molecules C2H6O)

molecules = 10.0 x ( 6.02 x 10²³ ) / 1

molecules = 6.02 x 10²⁴ / 1

=  6.02 x 10²⁴ molecules of C2H6O

Answer: \(6.023\times 10^{24}\)

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number \(6.023\times 10^{23}\) of particles.

As 1 mole of \(C_2H_6O\) molecule contains = \(6.023\times 10^{23}\) of molecules

Thus 10 mole of \(C_2H_6O\) molecule contains = \(\frac{6.023\times 10^{23}}{1}\times 10=6.023\times 10^{24}\) molecules

Thus the number of molecules are in 10.0 moles of \(C_2H_6O\) are \(6.023\times 10^{24}\)
