Which of the following solutions is the most dilute.
Colt1911 [192]

Answer:

d and e

Explanation:

We have 5 solutions with different molar concentrations, that is, the quotient between the number of moles of solute and the liters of solution. This can be expressed as mol/L or M. The most dilute would be the one having the less number of moles of solute per liters of solution, that is, solution d or e, which have the same concentration. If we order them from the most diluted to the most concentrated, we get:

d = e < a < b < c

A balloon starts out with a volume of 1.3 l at 115.3 kpa. if the temperature is held constant, what would the new volume be if t
Anna35 [415]

The new volume be if the pressure inside the balloon was reduced to 58kpa is 2.58 L.

<h3>What is ideal gas equation?</h3>

Ideal gas equation PV=nRT gives idea about the behavior of gases at different conditions and for this question the equation becomes:

P₁V₁ = P₂V₂, where

P₁ = initial pressure = 115.3 kpa

V₁ = initial volume = 1.3 L

P₂ = final pressure = 58 kpa

V₂ = final volume = ?

On putting all these values in the above equation, we get

V₂ = (115.3)(1.3) / (58) = 2.58 L

Hence resultant volume of gas is 2.58 L.

Can pressure affect the solubility of a substance in solution ? Explain
Tema [17]

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
