A) 112 ml
B) 56 ml
C) 224 ml
D) 336 ml
Correct Answer: C
Solution :
We know that \[2{{H}_{2}}{{O}_{2}}\,\,\to \,\,2{{H}_{2}}O+{{O}_{2}}\] \[\because \,\,\,2\,\,\times \,\,34\text{ }g\,\,\,\,\,\,\,\,~22400\text{ }ml\] \[\because \,2\,\,\times \,\,34 g =\, 68 g of {{H}_{2}}{{O}_{2}} liberates\] \[22400\text{ }ml\text{ }{{O}_{2}}\text{ }at\text{ }STP\] \[=\,\,\frac{0.68\times 22400}{68}\,\,=\,\,224\,ml\]
