If a solution having molarity M1and volume V1diluted such that its molarity becomes M2 and volume V2 , then we have , M1V1=M2V2. If two solutions having molarities M, M2 and volumes V1and V2 are mixed than the molarity of formed solution will be M=M1V1+M2V2/V1+V2.

1. The Conflict of Drivers In nature, there are two primary tendencies: Enthalpy ($Delta H$): Systems generally want to move toward a lower energy state (exothermic, $-Delta H$). Entropy ($Delta S$): Systems generally move toward a state of higher disorder (positive, $+Delta S$). The problem is that many processes are endothermic (absorbing heat) but still…
