a 23.74 mL volume of .0981 M NaOH was used to titrate 25 mL of a weak monoprotic acid solution to the stoichiometric point. determine the molar concentration of the weak acid solution. express in correct sig figs.

Answer 1

NaOH + HA ==> NaA + H2O
mols NaOH = M x L = ?
mols HA = mols NaOH (look at the coefficients)
M HA = mols HA/L HA
