Question

A sample of 0. 0255 mol potassium hydroxide, koh, was dissolved in water to yield 10. 0 ml of solution. Which amount would you need to change to solve for molarity?.

Answer 1

Step-by-step explanation:

To solve for molarity, you would need to change the volume of the solution.

Molarity is a measure of concentration in a solution, and it is calculated by dividing the number of moles of solute (in this case, potassium hydroxide) by the volume of the solution (in liters). The molarity of a solution is usually represented by the symbol "M".

In the given sample, the number of moles of potassium hydroxide (KOH) is 0.0255 mol, and the volume of the solution is 10.0 ml. To solve for the molarity of the solution, you would need to convert the volume from milliliters to liters, and then divide the number of moles of KOH by the volume of the solution in liters to calculate the molarity.

For example, to solve for the molarity of the solution, you could use the following formula:

M = (0.0255 mol KOH) / (10.0 ml / 1000 ml/L)

= 0.00255 M

This would give you the molarity of the solution as 0.00255 M.
