A) 4.444
B) 2.444
C) 3.344
D) 1.344
Correct Answer: D
Solution :
The number of g-equivalent of \[{{H}_{2}}{{O}_{2}}\] \[\equiv -g\] equivalent of \[{{\text{I}}_{\text{2}}}\] \[\equiv -g\]equivalent of \[N{{a}_{2}}{{S}_{2}}{{O}_{3}}\] Strength of 25 mL\[{{H}_{2}}{{O}_{2}}\]solution \[=\frac{20\times 0.3}{25}=0.24N\] \[=0.24\]g-equivalent \[{{O}_{2}}\] \[=0.24\times 5600mL{{O}_{2}}\]at STP in 1 L Volume strength\[=\frac{0.24\times 5600}{1000}=1.344mL\] \[=1.344\]You need to login to perform this action.
