Question

If 0.5 moles of solute are dissolved into 25 mL of solvent, what is the molarity of the resulting solution?Given:Find:Equation Used:Answer:

Answer 1

Answer:

20.0M

Explanations

Given the following parameters;

Moles of solute = 0.5moles

Volume of the solvent = 25mL = 0.025L

Required parameter

Molarity of the resulting solution

The formula for calculating the molarity of the solution is expressed as:

$M=\frac{n}{v}$

n is the moles of solute

v is the volume of solvent

Substitute the given parameters into the formula to have:

$\begin{gathered} M=\frac{0.5\text{moles}}{0.025L} \\ M=20.0M \end{gathered}$

Therefore the molarity of the resulting solution is 20.0M
