The main difference between gas pressure and vapour pressure is that gas pressure is exerted by the gases above the surface of a substance whereas vapour pressure is exerted by liquids above the surface of a substance
Molarity can be defined as the moles of solute in a liter of solution. The molarity of the salt solution is 
.
<h3>What is the relation between moles and volume?</h3>
The moles are the mass of substance with respect to the molar mass. The moles and volume relationship can be expressed in terms of molarity.
The molarity can be expressed as:
The given solution has,
- Moles of salt =
- The volume of solution =
L.
Substituting the values for molarity as:
The molarity of the solution is . Thus, option C is correct.

almost postive this is correct
Answer:
Option C. Energy Profile D
Explanation:
Data obtained from the question include:
Enthalpy change ΔH = 89.4 KJ/mol.
Enthalpy change (ΔH) is simply defined as the difference between the heat of product (Hp) and the heat of reactant (Hr). Mathematically, it is expressed as:
Enthalpy change (ΔH) = Heat of product (Hp) – Heat of reactant (Hr)
ΔH = Hp – Hr
Note: If the enthalpy change (ΔH) is positive, it means that the product has a higher heat content than the reactant.
If the enthalpy change (ΔH) is negative, it means that the reactant has a higher heat content than the product.
Now, considering the question given, the enthalpy change (ΔH) is 89.4 KJ/mol and it is a positive number indicating that the heat content of the product is higher than the heat content of the reactant.
Therefore, Energy Profile D satisfy the enthalpy change (ΔH) for the formation of CS2 as it indicates that the heat content of product is higher than the heat content of the reactant.
