If 0.250 liters of solution contains 0.030 moles of KOH, what is the molarity of the solution?
Were you given moles?
Yes No → divide by formula mass
Were you given liters?
Yes No divide by 1000 ml

Respuesta :

Answer: The molarity of KOH solution is 0.12 M

Explanation:

To calculate molarity of solution, we use the equation:

[tex]\text{Molarity}=\frac{\text{Number of moles}}{\text{Volume of solution( in L)}}[/tex]

We are given:

Moles of KOH solution = 0.030 moles

Volume of solution = 0.250 L

Putting values in above equation, we get:

[tex]\text{Molarity of KOH solution}=\frac{0.030mol}{0.250L}=0.12M[/tex]

Hence, the molarity of KOH solution is 0.12 M
