A sample of W (Mr = 134) of mass 1.97 g was dissolved in water and the resulting solution titrated
with 1.00 mol dm–3 NaOH.
29.4 cm3 of 1.00 mol dm–3 NaOH were required for complete neutralisation.
 (d) Use these data to deduce the number of carboxylic acid groups present in one molecule of W
W=C4H6O5

Compare moles of sample with moles of NaOH used for titration.
