What is the molarity of `Na^(+)` ions in a solution made by dissolving 4.20g of `NaHCO_(3)` (M=`84.0`) and 12.6g of `Na_(2)CO_(3)` (M=126) in water and diluting to `1.00`L?

10 " mL of " 2 M HCl and 20 " mL of " 1 M HNO_3 and V volume of 5M H_2SO_4 are mixed together and the solution was made upto 5 L. 10 " mL of " this acid solution exactly neutralises 28.6 " mL of " Na_2CO_3 solution containing 1 g of Na_2CO_4.10H_2O in 100 " mL of " water. Calculate the amount of SO_4^(2-) ions in grams present in solution.
