Question

6.8g of h2o2 is present in 500ml of an aqueous solution. When 10ml of this solution is decomposed, what is the volume of the o2

Answer 1

Answer:

Explanation:

h2o2=h2o+1/2o2

equivalent of h2o2  = 6.8/34*2

=0.4

for 500 ml it is 0.4

10 ml  0.008

equivalent = 0.008

v/22.4*2=0.008

v=0.0896 lt

v=89.6 ml
