Astudent obtained a 0.4513g sample containing aspirin. this sample was analyzed through a titration with naoh and phenolphthalein was used as the indicator. the endpoint (ph around 9) for the reaction was reached after the addition of 15.22 ml of 0.1105m naoh. molar mass for aspirin = 180.16g/mol.
calculate the % purity for the sample. show all your work
*hint: aspirin reacts with naoh in a 1: 1 ratio.
% purity = (actual moles of aspirin in sample based on titration÷ maximum moles of aspirin in sample) × 100%
