Question

An organic compound contains C=32%,H=4%O=64%.the molecular formula is

Answer 1

Answer:

calculate the no of moles of each element in compound

no of moles of carbon=32/12=2.66

no of moles of hydrogen=4/1=4

no of moles of oxygen = 64/16=4

then find ratio of no of moles carbon:hydrogen:oxygen

2.6:4:4=1.3:2:2=1.95:3:3

therefore emperical formula is C2H3O3.
