The osmotic pressure of a solution is a colligative property, which means that it depends on the number of particles of solute in the solution.

Formula: Osmotic pressure = MRT, where M is the molarity of the solution, R is the universal constant of ideal gases and T is the absolute temperature of the solution.

So, the answer is the option .: the osmotic pressure of a solution increases as the number of particles of solute in the solution increases.

<h2>The answer is option C Explanation: Basically more solute particles will require the solvent to rush in through the semipermeable membrane to fix the high concentration creating a difference in volume between two sides of that membrane. And to even out the volumes on both sides, more (osmosis) pressure will be needed to push down on the solution with higher volume. Anyways, its too confusing to explain, the answer is C and that’s all that matters.</h2>

1. What does it mean for a substance to be soluble?

Anni [7]

Answer:

Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. ... Certain substances are soluble in all proportions with a given solvent, such as ethanol in water.

Answer:

$1.32\times 10^{-3} mol/L$ is the solubility of nitrogen gas in a diver's blood.

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{N_2}=K_H\times p_{liquid}$

where,

$K_H$ = Henry's constant = $6.26 \times 10^{-4}mol/L.atm$

$p_{N_2}$ = partial pressure of nitrogen

$p_{N_2}= P\times \chi_{N_2}$ (Raoult's law)

$=2.71 atm\times 0.78=2.1138 atm$

$C_{N_2}=6.26 \times 10^{-4}mol/L.atm\times 2.1138 atm$

$C_{N_2}=1.32\times 10^{-3} mol/L$

$1.32\times 10^{-3} mol/L$ is the solubility of nitrogen gas in a diver's blood.

mrs_skeptik [129]

Answer:

Hey, I hope this helps. You gave the equation already balanced so there was no need to do so, the next thing we need to do after balancing is to split the strong electrolytes into ions. Once that is completed we cross off any reoccurring ions. That leaves us with our complete net ionic.

I also recommend you check out Wayne Breslyn on Yt. He is so helpful with equations like these.
