A sample of 0.0255 mol potassium hydroxide, KOH, was dissolved in water to yield 0.0100 L of solution. What is the molarity of the solution?
To calculate the molarity of the solution, we use the formula:
Molarity (M) = moles of solute / volume of solution in liters
Given:
moles of potassium hydroxide (KOH) = 0.0255 mol
volume of solution = 0.0100 L
Plugging in the values:
Molarity (M) = 0.0255 mol / 0.0100 L
Molarity (M) = 2.55 mol/L
Therefore, the molarity of the solution is 2.55 M.
