The initial mass of aspirin sample I measured was 0.1027 g and the absorbance of aspirin sample was 0.455.
From there, how would I find the moles of salicylic acid in aspirin sample (mol) and the mass of salicylic acid in aspirin sample (g), which should help me calculate the percent purity of aspirin and the percent yield of aspirin in sample. Thank you.
