Solve 2. Lisa, a librarian at the Knights of Favonius, is also a great potion maker. She wants to create a potioncontaining potassium dichromate (K2Cr207). The only available solutions in her laboratory are 21.0 mL of0.650 M solution and 27.0 mL of 0.350 M solution.a. What is the concentration of potassium dichromate (in M) when the two solutions are combined?/D. Wrial is its concentration in % w/v?'c. For this potion to have a stronger effect, Lisa wants it to have a concentration of 20.0 % w/v. Can shecreate it based on combining the available solutions alone? (d. Lisa only settled to produce the lesser potent potion with 10.0 % w/v. How much water will she add (inmL) to achieve this concentration?

When two solutions of potassium dichromate, K2Cr2O7 are added, both the moles and volumes are added…
