– ethyl acetate concentration problem/answers –

The concentration of (CH,COOC2Hs) in a sample was O Are determined by diluting 10.00 mL sample to 100.00 mL. A volume of 20.00 mL of this diluted solution was refluxed with 45.00 mL, of 0.05000 M KOH solution. The reaction is as follow er cooling, the excess OH was back titrated with 3.50 mL of 0.05000 M H2SO4 solution. Calculate the weight of ethyl acetate per 100 mL in the initial sample
