Question

The mole to mole ratio of hydrogen peroxide to oxygen is 2:1. Use this and 5.56 x 10 ^23 molecules of hydrogen peroxide present to determine the liters of oxygen produced at room temp.

Answer 1

*@RTP= 25.4

Answer 2

ok so just use:
n=N/L
where :
n - moles of atoms/molecules
N - number of atoms/molecules
L - 6,022 * 10^23 mol-1

and then:
n(H2O2)/n(O2) = 2/1
n(H2O2) = 2*n(O2)

and then:

n=V/Vm
V= n*Vm

where

V - volume
n - number of moles
Vm - as you wrote 25,4 dm3mol-1

Answer 3

Can you help me through it?

Answer 4

just put numbers in those equations...

Answer 5

For the first one, L, wouldnt it be 6.02 x 10^23?

Answer 6

yes
