titration of 25ml of Na2CO3 with 0.352mol/l HCl of 15.2ml what is the molar concetraion of sodium carbonate

Answer 1

Na2CO3 + 2HCl ==> 2NaCl + H2O + H2O
mol HCl = M x L = ?
Convert mol HCl to mol Na2CO3 using the coefficients in the balanced equation.
?mol HCl x (1 mol Na2CO3/2 mol HCl) = ?mol HCl x 1/2 = xx mol Na2CO3.

M Na2CO3 = mol Na2CO3/L Na2CO3.
