B

`5 xx 10^(-2)`

C

`10xx10^(-2)`

D

`1.5 xx 10^(-2)`

0.58 g of CH_3(CH_2)_(c)COOH was burnt in excess air and the resulting gases (CO_2 and H_2O ) were passed through excess NaOH solution. The resulting solution was divided into two equal parts. One part requires 50 " mL of " 1.0 M HCl for complete neutralisation using phenolphthalein indicator. Another part required 80 " mL of " same HCl for neutralisation using methyl orange as indicator. Calculate the value of n and the amount of excess NaOH solution taken initially.

0.1g of a solution containing Na_(2)CO_(3) and NaHCO_(3) requires 10mL of 0.01 N HCl for neutralization using phenolphthalein as an indicator, mass% of Na_(2)CO_(3) in solution is:

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. The number of moles of CO present initially is
