Question

How many molecules are in 10.0 moles of c2h6o?

Answer 1

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 2

Answer:
`6.023* 10^(24)`

Step-by-step explanation:

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

As 1 mole of
`C_2H_6O` molecule contains =
`6.023* 10^(23)` of molecules

Thus 10 mole of
`C_2H_6O` molecule contains =
`(6.023* 10^(23))/(1)* 10=6.023* 10^(24)` molecules

Thus the number of molecules are in 10.0 moles of
`C_2H_6O` are
`6.023* 10^(24)`
