A mixture of CO and `CO_(2)` when treated with `I_(2)O_(5)` gives `I_(2)` vapours accoeding to the following equation:
`5CO+I_(2)O_(5)to5CO_(2)+I_(2)`
`I_(2)` vapour was separated and treated with `HClO_(4)` and the resultant `HIO_(4)` required 0.001 " mol of "hlycerol for complete oxidation. After treatment with `I_(2)O_(5)` and removal of `I_(2)` ,t he mixture was treated with excess of 0.1 N NaOH solution and finally this solution required 20 " mL of " 1 N HCl to reach end point using phenolphthalein as indicator, followed by methyl orange as indicator after the first end point, 10 " mL of " further HCl was consumed.
Q. Total number of millimoles of `CO_(2)` in the above problem is

Options

A. 5
B. 10
C. 50
D. 100

Answer

B

Explanation

Total m moles of `CO_(2)=(n+5)=5+5=10m mol`
