Igcse Model Questions Vol1 2024 Chemistry Question 16
Practice objective / multiple choice question 16 from the 2024 Igcse Model Questions Vol1 Chemistry examination.
Propanoic acid ((C_3H_6O_2), molar mass 74.08 g mol(^{-1})) is reacted with excess ethanol in the presence of (H_2SO_4) to form ethyl propanoate. During the reaction 10 % of the acid is lost to a side polymerisation, and the isolated product is only 70 % pure by mass. If 5.00 g of propanoic acid is mixed with 8.0 g of ethanol (molar mass 46.07 g mol(^{-1})), calculate the mass of pure ethyl propanoate obtained. (Molar mass of ethyl propanoate = 102.13 g mol(^{-1})).
