C3HNO

Explanation:

Organic molecules are molecules that are found in living organisms. They are characterised by the presence of carbon atoms (C). These could be in the form of linear chains or cyclic structures. In general, the C atoms in organic molecules can be linked to other C atoms or to hetero atoms like oxygen (O), nitrogen (N), sulfur (S), halides etc.

Based on the given options: C3HNO contains C, H, N and O and best fits the description and characteristics of an organic molecule

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
