Compare the composition of sucrose purified from the sugar cane with the composition of sucrose purified from sugar beets.

Answer: they are the same.

Explanation:

1) Sucrose is a compound with chemical formula C₁₂H₂₂O₁₁

2) That means that all molcules of sucrose will have the same kind of atoms in the same proportion, whic is to say same composition:

12 atoms of C: 22 atoms of H: 11 atoms of O, per each molecule of sucrose.

3) For this question you can rely in the definition of compound: a pure substance formed by the combination of two or more elements always in the same ratio (same composition).

4) That also implies, that all the molecules of sucrose have the same properties.

The problem ask to compare the composition of sucrose purified from the sugar cane with the composition of sucrose purified from beets and the answer is that the two sucrose molecule will be chemically and structurally the same. I hope you are satisfied with my answer and feel free to ask for more
