19. Example
24.55 g
52.2 mL
0.990 g/mL

20. ? g (theoretical) = mol C2H5OH x 46.07 g/mol = 13.22 g
Molar mass = g/mol
Molar mass = g/mol
? mol C2H5OH = 4 x mol sucrose
= mol
? mol sucrose = g / g/mol
= mol
? g (theoretical) = mol C2H5OH x g/mol
= g
__________________
? g (actual) = [%5,that is:] 5/100 x 52.2 mL x g/mL
= 2.58 g
% Yield = g (actual) / g (theoretical) x 100
= 19.5 %
