A) 250 ml
B) 300 ml
C) 150 ml
D) 200 ml
Correct Answer: B
Solution :
Quantity of \[{{H}_{2}}{{O}_{2}}=15\,ml\] and volume of \[{{H}_{2}}{{O}_{2}}=20\] We know that 20 volume of \[{{H}_{2}}{{O}_{2}}\] means 1 litre of this solution will give 20 litre of oxygen at N.T.P. Since, oxygen liberated from 1000 ml (1 litre) of \[{{H}_{2}}{{O}_{2}}=20\,litre\], therefore oxygen liberate from 15 ml of \[{{H}_{2}}{{O}_{2}}\] \[=\frac{20}{1000}\times 15=0.3\,litre=300\,ml\]
