sodium chloride and glucose both are soluble in water but the solubility of NaCl is greater then glucose why.

Answers

The solubility of a substance in water depends on several factors, including the nature of the solute and solvent, as well as the intermolecular forces involved.

In the case of sodium chloride (NaCl) and glucose, both substances are indeed soluble in water. However, the solubility of NaCl is generally greater than that of glucose due to differences in their chemical properties.

NaCl is an ionic compound, meaning it consists of positive sodium ions (Na+) and negative chloride ions (Cl-). When NaCl is added to water, the polar water molecules surround the ions and separate them from the crystal lattice. These water molecules form favorable interactions with the charged ions through ion-dipole attractions, resulting in the dissolution of NaCl in water. These strong ion-dipole forces contribute to the high solubility of NaCl in water.

On the other hand, glucose is a covalent compound composed of carbon, hydrogen, and oxygen atoms. It does not dissociate into ions when dissolved in water. Instead, glucose molecules interact with water through weaker intermolecular forces such as hydrogen bonding and dipole-dipole interactions. While these forces allow glucose to dissolve in water, they are relatively weaker than the ion-dipole interactions in NaCl-water solution. As a result, glucose has a lower solubility compared to NaCl in water.

Therefore, the differing chemical properties of sodium chloride and glucose contribute to the higher solubility of NaCl in water compared to glucose.

Use the mole concept to calculate the number of atoms that are in a 1.75-mol sample of CHCl3.

Answers

This is how I got to that answer. Since we don't know how many atoms there are in a mole, we use the number 6.02 x 10^-23. Now, just plug in what you have in the equation: 

1.75 moles ChCl3 x (6.02 x 10 ^-23) / 1 mole = 1.0535 x 10^-22 atoms.

find the solution below

What is the molarity of a solution where 1.00 gram of NaCl (MM 58.5 g/mol)is dissolved in enough water to make 415 mL of solution?
a. 4.12 x 10-5 M

b. 7.09 x 10-3 M

c. 4.12 x 10-2 M

d. 2.41 M

Answers

To find the molarity of the solution, we need to use the formula:

Molarity (M) = moles of solute / volume of solution (in liters)

First, let's calculate the number of moles of NaCl using its molar mass (MM):

Mass of NaCl = 1.00 gram

Molar mass of NaCl = 58.5 g/mol

Moles of NaCl = Mass of NaCl / Molar mass of NaCl

= 1.00 g / 58.5 g/mol

≈ 0.0171 mol

Next, we need to convert the volume of the solution from milliliters (mL) to liters (L):

Volume of solution = 415 mL = 415 / 1000 L

= 0.415 L

Now, we can calculate the molarity:

Molarity (M) = moles of solute / volume of solution

= 0.0171 mol / 0.415 L

≈ 0.0412 M

Therefore, the molarity of the solution is approximately 0.0412 M.

The closest answer option is c. 4.12 x 10^-2 M.

I hope this explanation helps! Let me know if you have any further questions.
