When a mixture of KI and KCl is heated repeatedly with `H_(2)SO_(4)`, iodine escapes completely and `K_(2)SO_(4)` is produced quantitatively. In case of such a mixture, it is observed that the mass of `K_(2)SO_(4)` is equal to the mass of the mixture of KI and KCl taken. what is the ratio of the masses of KI and KCl in this mixture?

Find the molarr mass of Na_(2)SO_(4) .

If the ratio of masses of CH_(4) and N_(2) in a gaseous mixture is 1 : 4 then what will be the ratio of number of molecules of them in the mixture ?

When a mixture of NaCl and NaBr is heated with H_(2)SO_(4) , the halogen components are liberated as their hydracids leaving Na_(2)SO_(4) as the residue. In an experiment, the mass of Na_(2)SO_(4) left is equal to the mass of (NaCl+NaBr) taken at the begining of the experiment. calculate the percentages of NaCl and NaBr in the given mixture.
