Plants that thrive in saltwater must have internal solutions (inside the plant cell) that are isotonic (same osmotic pressure) as the surrounding solutions. A leaf of a saltwater plant thrives in an aqueous 25 °C solution (d = 1.025 g/L at 25 °C) that has a freezing point depression equal to –0.621 °C. What is the osmotic pressure of the leaf? Note: you will need to make some assumptions to complete this problem. Please state any assumptions you made

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.
