77. Solving a chemistry problem

6. Determine the mass of the substance contained in V liters of solution at a temperature of 25 ° C, if the osmotic pressure of the solution is 5.5 KPa. The molar mass of a substance (M) and its isotonic coefficient (i) are given

Task: V 0.7 l; M 80 g/mol; i 2.2

When solving this task, pay special attention to the fact that all quantities are expressed in one system of units (preferably, the international system of units SI). In addition, it is desirable that you write about the biological significance of osmosis, about the use of isotonic solutions in medicine.
