Question

How many molecules are in 7.9 mol of H202

Answer 1

Answer: There are
`47.6* 10^(23)` molecules in 7.9 mol of
`H_2O_2`

Step-by-step explanation:

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

1 mole of
`H_2O_2` molecule contains =
`6.023* 10^(23)` molecules

Thus 7.9 mole of
`H_2O_2` molecule contains =
`(6.023* 10^(23))/(1)* 7.9=47.6* 10^(23)` molecules

Thus there are
`47.6* 10^(23)` molecules in 7.9 mol of
`H_2O_2`
