`0.50 g` of a mixture of `K_(2)CO_(3)` and `Li_(2)CO_(3)` required `30 mL` of `0.25 N HCl` solution for neutralization. What is `%` composition of mixure?

0.5 g of a mixture of K_2CO_3 and Li_2CO_3 requires 15 " mL of " 0.25 N Hci for neutralisaion. Calculate the percentage composition of the mixture.

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:

1g mixture of equal number of mole of Li_(2)CO_(3) and other metal carbonate (M_(2)CO_(3)) required 21.6mL of 0.5 N HCl for complete neutralisation reaction. What is the apoproximate atomic mass of the other metal?

1 g of impure Na_(2)CO_(3) is dissolved in water and the solution is made upto 250 mL . To 50 mL of this solution, 50 mL of 0.1 N HCl is added and the mixture after shaking well required 10 mL of 0.16 N NaOH solution for complete neutralization. Calculation percent purity of the sample of Na_(2) CO_(3) .

1g of a mixture of equal number of moles of Li_(2)CO_(3) "and" M_(2)CO_(3). Required 44.44 ml of 0.5 M HCl for completion of the reactions, Li_(2)CO_(3)+2HClrarr2LiCl+H_(2)O+CO_(2) M_(2)CO_(3)+2HClrarr2MCl+H_(2)O+CO_(2) If the atomic mass of Li is 7, then find the Atomic mass of M.
