Question

Care este Procentul de carbon din compus care rezulta in urma reactiei dintre acidul acetic si etanol?

Answer 1

CH3-COOH + C2H5-OH=CH3-COO-C2H5+H2O

CH3COOC2H5=C4H8O2

M C4H8O2=4AC+8AH+2AO=88g/mol

%C=4AC*100/88=54,545%

Answer 2

CH₃-COOH+CH₃-CH₂-OH--->CH₃-COO-CH₂-CH₃ + H₂O

MC4H8O₂=4*12+8*1+16*2=48+8+32=88
88g C₃H₆O₂..............48g C
100g C₃H₆O₂...............x

x=(48*100)/88=54,54% C
