2. Lisa, a librarian at the Knights of Favonius, is also a great potion maker. She wants to create a potion containing potassium dichromate (K₂Cr2O7). The only available solutions in her laboratory are 21.0 mL of 0.650 M solution and 27.0 mL of 0.350 M solution. d. Lisa only settled to produce the lesser potent potion with 10.0 % w/v. How much water will she add (in mL) to achieve this concentration?

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
