How many Sucrose molecules in 3.0 moles of sucrose?
There are 1.81 x 10^24 sucrose molecules in 3.0 moles of sucrose.
Why do sucrose molecules associate with water?
Sucrose molecules associate with water because they are polar, with both positive and negative charges. Water molecules are also polar, so they are attracted to the charged regions on the sucrose molecules, forming hydrogen bonds. This interaction between sucrose and water allows sucrose to dissolve in water.
Sucrose is soluble in water because the attractive forces between the solute particles are greater than the attractive forces between the solute and the solvent particles.?
You've got it in reverse. When sucrose dissolves in water, sucrose is the solute, and water is the solvent. In order to dissolve, sucrose molecules have to be more attracted to water molecules than they are to other sucrose molecules. If the attraction of sucrose to sucrose was greater than the attraction of sucrose to water, then there would be no reason for the solid sucrose to turn into the aqueous sucrose solution. Sucrose molecules would simply remain firmly attached to each other if that were the case.

What happens when sucrose dissolves in 200ml of water?
When sucrose dissolves in water, the sucrose molecules are surrounded by water molecules which break the bonds in the sucrose molecule, separating it into its constituent glucose and fructose molecules. The resulting solution is a homogeneous mixture known as a sugar solution.
Are water and sucrose protein molecules?
No they are not.
What is the correct order by size of the following molecules water sucrose glucose and protein?
The correct order by size of the molecules listed would be protein > sucrose > glucose > water. Proteins are the largest molecules, followed by sucrose (a disaccharide), glucose (a monosaccharide), and then water.
Is sucrose molecules bigger than glucose molecules?
Yes, sucrose molecules are larger than glucose molecules. Sucrose is a disaccharide composed of one glucose molecule and one fructose molecule, while glucose is a monosaccharide. This difference in structure accounts for the difference in size between the two molecules.
What happens to sucrose molecules when heated?
new molecules starts to form
How many sucrose molecules are in 3.0 moles of sucrose?
To find the number of sucrose molecules in 3.0 moles of sucrose, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) molecules per mole. Multiply the number of moles by Avogadro's number: [ 3.0 , \text{moles} \times 6.022 \times 10^{23} , \text{molecules/mole} \approx 1.81 \times 10^{24} , \text{molecules}. ] Therefore, there are approximately (1.81 \times 10^{24}) molecules of sucrose in 3.0 moles.
How many monosaccharide molecules are needed to form one sucrose molecule?
Two monosaccharide molecules are needed to form one sucrose molecule.
What can you conclude about the permeability of potato cytoplasm with respect to sucrose and water molecules?
The permeability of potato cytoplasm to water molecules is high, allowing water to easily move in and out of the cell. However, the permeability to sucrose molecules is lower, as they require specific transport proteins to pass through the cell membrane. This difference in permeability affects how sucrose and water move across the cell membrane in potatoes.
