If 2M, 200ml HCl, 2M, 100ml `CaCl_(2)` and 5M, 200ml `AlCl_(3)` is mixed then final concentration of `Cl^(-)` will be:

100 ml, 1.5M Fe(NO_(3))_(3) . 100 ml, 2M FeCl_(3) , 100 ml 2M Mg(NO_(3))_(2) are mixed and 700 ml water is added. The molar concentration of total ions in the solution in ______M

2 M of 100 ml Na_(2)SO_(4) is mexed with 3 M of 100 ml NaCl solution and 1 M of 200 ml CaCl_(2) solution. Then the ratio of the concentration of cation and anion.

100 ml of 1M HCl, 200 ml 2 M HCl and 300 ml 3M HCl are mixed. The Molarity of the resulting solution is

200 ml of 1M H_2 SO_4 , 300 ml 3M HCl and 100 ml of 2M HCI are mixed and made up to 1 litre. The proton concentration in the resulting solution is

"0.5 g NaOH" was added to "200 ml 0.1 M HCl" , final concentration of reactant left is :

"0.5 g NaOH" was added to "200 ml 0.1 M HCl" , final concentration of reactant left is :

2 M of 100 mL Na_2 SO_4 is mixed with 3 M of 100 mL NaCl solution and 1 M of 200 mL CaCl_2 solution . Then the ratio of the concentration of cation and anion is

100 ml of 1M HCI, 200 ml of 2M HCl and 300 ml of 3M HCl are mixed with enough water to get 1M solution. The volume of water to be added is (in ml)
