`0.7 g "of" Na_(2)CO_(3).xH_(2)O` were dissolved in water and the volume was made to `100 mL, 20 mL` of this solution required `19.8 mL "of" N//10 HCl` for complete neutralization. The value of `x` is:

0.70 g of a sample of Na_(2)CO_(3).xH_(2)O were dissolved in water and the volume was made to 100 ml. 20 ml of this solution required 19.8 ml of (N/10) HCl for complete neutralisation. The value of x is

3.150 g of oxalic acid [(COOH)_(2).xH_(2)O] are dissolved in water and volume made up to 500 mL . On titration 28 mL of this solution required 35 mL of 0.08N NaOH solution for complete neutralization. Find the value of x .

4.0 g of a mixture of Nacl and Na_(2) CO_(3) was dissolved in water and volume made up to 250 mL . 25 mL of this solution required 50 mL of N//10 HCl for complete neutralisation. Calculate the percentage composition of the original mixture.
