34.1 mg NaCl in 117.3 mL of solution
Solnce55 [7]

The molarity of the solution will be 4.97 M.

<h3>What is molarity?</h3>

It is the number of moles of solutes per 1 liter of solvent or solution.

Mole of 34.1 g NaCl = 34.1/58.44 = 0.5835 mol

117.3 mL = 117.3/1000 = 0.1173 L

Molarity of the solution = 0.5835/0.1173 = 4.97 M

What is the morality of a solution made with 0.88 moles of KCl and 2.0 L of water?
Anarel [89]

Answer:

M=0.44M

Explanation:

Hello,

In this case, the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:

M=\frac{n_{solute}}{V_{solution}}

In this case, the solute is the KCl (potassium chloride) and the solution is made up of both water and KCl. Moreover, since during this type of dissolution processes, the volume of the solution is not significantly affected by the addition of the solute, the resulting molarity is:

M=\frac{0.88mol}{2.0L}\\ \\M=0.44M

Best regards.
