The mass of a mixture containing `HCI and H_2 SO_4` is `0.1g` On treatment with an excess of an `AgNO_3` solution , reacted with this acid mixture given `0.1435g` of `AgCI`. Mass % of the `H_2SO_4` mixture is :

A gaseous mixture containing He, CH_(4) and SO_(2) in 1:2:3 mole ratio, calculate the molar ratio of gases effusing out initially.

The pH of a solution of H_(2)SO_(4) is 1. Assuming complete ionisation, find the molarity of H_(2)SO_(4) solution :

A mixture of NH_4 NO_3 and (NH_4)_2 HPO_4 contain 30.40% mass per centof nitrogen. What is the mass ratio of the two components in the mixture ?

Gram molecular mass of H_(2)SO_(4) is

Aniline upon heating with conc. HNO_3 and conc. H_2SO_4 mixture gives:

A mixture of H_(2)SO_(4) and H_(2)C_(2)O_(4) (oxalic acid ) and some inert impurity weighing 3.185 g was dessolved in water and the solution made up to 1litre. 10 mL of this solution required 3 mL of 0.1 N NaOH for complete neutralization. In another experiment 100 mL of the same solution in hot condition required 4 mL of 0.02 M KMnO_(4) solution for complete reaction. The mass % of H_(2)SO_(4) in the mixture was:

A solution containing 2.675 g of CoCl_3 .6NH_3 (molar mass = 267.5 g mol^-1 ) is passed through a cation exchanger. The chloride ions obtained in solution were treated with excess of AgNO_3 to give 4.78 g of AgCl (molar mass = 143.5 g mol^-1 ). The formula of the complex is : (At. mass of Ag = 108 u)

A mixture contains N_(2)O_(4) and NO_(2) in the ratio 2:1 by volume. The vapour density of the mixture is:
