Percent composition of C(carbon)=total mass of carbon in -C9H804 *100/ molar mass of C9H8O4 =12*9*100/12*9+1*8+16*4= 60% Percent composition of H (hydrogen)=total mass of hydrogen in C9H8O4*100/molar mass of C9H8O4 =8*100/180=4.5% Percent composition of O(oxygen)=mass of O in C9H8O4*100/ molar mass of C9H8O4 =16*4*100/180 =35.5%
