Question

If 0.15 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

We are asked to find the molarity which is defined as the moles of solute per liter of solution. Now, according to the form of response that they ask us, we have.

They provide us with two data, the moles of solute and the milliliters of solution, these milliliters must be converted to liters. So the given data will be:

Moles of solute=0.15mol

Liters of solution=25mL x(1L/1000mL)=0.025L

Now, the mathematical representation of molarity is:

`\text{Molarity}=\frac{\text{Moles of solute}}{Liters\text{ of solution}}`

If we substitute the given values we have:

`\text{Molarity}=\frac{\text{0}.15\text{mol}}{0.025L}=6M`

So, in summarizing the complete answer will be:

*Given:

Moles of solute=0.15mol

Liters of solution=25mL x(1L/1000mL)=0.025L

*Find:

Molarity of the resulting solution

*Equation used:

`\text{Molarity}=\frac{\text{Moles of solute}}{Liters\text{ of solution}}`

*answer: The molarity of the resulting solution is 6M
