How is molarity of a solution determined

The volume does not need to be converted to liters yet because both sides of the equation use mL. If In order for the scientist to make Water was added to 25 mL of a stock solution of 5.

What is the molarity of the new solution? We are asked to find c 2 , which is the molarity of the diluted solution. Notice that all of the units for volume have been converted to liters.

We calculate that we will have a 0. Boundless vets and curates high-quality, openly licensed content from around the Internet. This particular resource used the following sources:. Skip to main content. In a laboratory situation, a chemist must frequently prepare a given volume of solutions of a known molarity. The task is to calculate the mass of the solute that is necessary. The molarity equation can be rearranged to solve for moles, which can then be converted to grams.

See sample problem A chemist needs to prepare 3. What mass of KMnO 4 does she need to make the solution? Moles of solute is calculated by multiplying molarity by liters. Then, moles is converted to grams. When g of potassium permanganate is dissolved into water to make 3.
