All carbohydrates are made up of carbon, oxygen, and hydrogen.
The chemical formula for Glucose is

.
The chemical formula for Fructose is the same as that of Glucose. The difference between the two is how they are structured.
The chemical formula for Sucrose is

.
As you can see in the chemical formulas of Glucose, Fructose, and Sucrose, they are all made up of the elements carbon, hydrogen, and oxygen.
Answer:
I would say chordates. (Not absolutely sure so double check)
Explanation:

Answer:
The correct answer is: the mass in grams of one mole of a substance
Explanation:
The molar mass of a given substance corresponds to the mass of one mole of this in grams. Corresponds to a physical property of the substance. Example: the molar mass of water (H20) is:
Molar mass H20 = (Mass H) x 2 + Mass 0 = 2 x 1 g + 16 g = 18 g / mol
