Please see question 28, just the top one. I figure in this system the pressure is changing and my answer is the original pressure divided by the final pressure is equal to X.  Do I have this correct?     pv= nRT      N and T and R are constants   thus P1V1 = P2V2.

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.
