Question

Mole fraction of water in 20% aq. Solution of h2o2

Answer 1

Explanation:

h2o2 = 20%

so, h2o in that solution = 80%

mole fraction = moles of solute / (moles of solute + moles of solvent)

moles of h2o = 80/18 (h2 =2 +o=16)

=4.44

moles of h2o2 = 20/34 (h2=2+o2=32)

=0.58

mole fraction = 4.44/(0.58+4.44)

=4.44/5.02

=0.88
