BUSvo. In a reaction 5.39. of sodium carbonate reacted with 6 g, of ethanoic acid. The product were 2.2 g o!corbon dioxide, 0.9 g. of water and some sodium ethanoate. What is the expected weight of sodiumethanoate? Prove that this date is in agreement with law of conservation of mass. |
Answer» Answer:LAW OF CONSERVATION OF MASS:law of conservation of mass states that the total weight of reactants is equal to the total weight of products formed .Na2CO3 + CH3COOH = H2O+ CO2+CH3COONa(5.39) ( 6g) (0.9g) (2.2) (x)ACCORDING to LAW of CONSERVATION of MASS ,5.39 + 6.0 = 0.9 + 2.2 + x11.39 = 3.1 + x=> x = 11.39 - 3.1 = 8.29g∴ expected weight of sodium ethanoate = 8.29g |
