Answer:
Empirical formula is C3H3O
Molecular formula C9H9O3
Explanation:
From the question given, we obtained the following data:
Carbon = 63.15%
Hydrogen = 5.30%
Oxygen = 31.55%
We can obtain the empirical and molecular formula by doing the following as illustrated in the attached file. Please see attachment for explanation.

Answer: The type of molecule that supports a tree's tall structure is A. polysaccharide.
Explanation:
Polysaccharides are macromolecules consisting of many monosaccharide units. The Oxygen- hydrogen groups that make up the monomers such as glucose can form hydrogen bonds with cellulose molecules. These hydrogen bonds formed, allows for the cellulose strands to form fibres, providing trees and other plants.
Therefore, polysaccharides are molecules that supports a tree's tall structure.
In dilution problems involving known concentrations and volumes of the solution, a widely used equation is:
C1V1 = C2V2
Where:
C1 = Concentration of Solution 1
V1 = Volume of Solution 1
C2 = Concentration of Solution 2
V2 = Volume of Solution 2
Substituting the given values gives: (2.35 M)*(250mL) = (15.0 M)*V2
<span>V2 = 39.17 mL
</span>
So, you must initially have 39.17 mL of 15 M solution and dilute it to 250 mL to achieve a 2.35 M solution
