Answer:
% composotion of an element in a compound is
% composotion of an element in a compound is Atomic massofelement*100/Molecularmass of compound
Mol mas of urea =60
% of C in urea = 12*100/60 =20%
% of O inurea = 16*100/60 =26.6%
Two nitrogen atoms and four hydrogen atoms
% of N in urea = 14*2*100/60=46.6%
% of H in urea = 1*4*100/60=6.6%
Similarly other compounds composition can be calculated.
