Calculate the normality of a solution containing 13.4 g fo sodium oxal

1.	Calculate the normality of a solution containing 13.4 g fo sodium oxalate in 100mL solution.
Answer» Normality = `("wt. in g/eq. wt")/("vol. of solution in litre")` Here, eq. wt. of `Na_(2)C_(2)O_(4)=134//2=67` so `N=(13.4//67)/(100//1000)=2N`
