find the percentage composition of sucrose

Answer 1

 Best Answer

total molar mass of sucrose is 12*12+22*1+11*16 = 342 

% of mass of C in sucrose is 144/342*100 = 42.1% 
% of mass of O in sucrose 176/342*100 = 51.5% 
% of mass of h in sucrose 22/342*100 = 6.5%

Answer 2

C12,H22,O11 is the percentage composition of sucrose
