A 2.00g sample of acetylsalicylic acid, better known asaspirin, is dissolved in

Question

A 2.00g sample of acetylsalicylic acid, better known asaspirin, is dissolved in 100mL of water and titrated with0.200mol/L NaOH(aq) to the end point. The volume of base requiredis 55.5mL. Calculate the molar mass of acetylsalicylic acid, whichhas one dissociable proton per molecule. Please show all work!

Explanation / Answer

Wt. of acetylsalicylic acid,w=2.00g Vol. of acetylsalicylic acid prepared,Vml=100mL                 Concentration of base,M 2 =0.200 M Vol. of baserequired,V 2 =55.5 mL M 1* V 1 = M 2* V2 [(Wt /Mol. wt.)*(1000/Vml)]*VmL =M 2 * V2 On substitution Mol. wt. of acetylsalicylic acid=180.18 On substitution Mol. wt. of acetylsalicylic acid=180.18
