What is the molarity of 2.3 mol of Kl dissolved in 0.5 L of water
Nastasia [14]

Answer:

4.6\,\,moL\,\,L^{-1}

Explanation:

Molarity refers to a measure of concentration.

Molarity = moles of solute/Litres of solution

Molarity refers to number of moles of solute present in this solution.

In order to find a solution's molarity, use value for the number of moles of solute  and the total volume of the solution expressed in liters

As molarity of 2.3 mol of Kl is dissolved in 0.5 L of water,

Molarity = \frac{2.3}{0.5} =4.6\,\,moL\,\,L^{-1}

Because water molecules are polar and carbon dioxide molecules are nonpolar,
Gala2k [10]

The correct is D.

Water is a polar molecule and it has polar bonds, which carry partially positive and partially negative charges. This polar bond increases the attraction between molecules of water and thus it requires a greater energy to break the bond between the molecules of water compare to carbon dioxide, which is a non polar molecule. Thus, water has a higher boiling point than carbon dioxide.
