A) 6
B) 5
C) 3
D) 8
Correct Answer: D
Solution :
stock solution of HCl =29.2%(w/w) Molarity of stock solution of HCl = \[\frac{29.2\times 1000\times 1.25}{36.5\times 100}\] If volume of stock solution required = V ml \[V\times \frac{29.2}{36.5}\times \frac{1000}{80}=200\times 0.4\Rightarrow V=8ml\]You need to login to perform this action.
