bokep Bismillahirohmanirohim Assalamualaikum warahmatullahi wabarakatuh hopefully you are always healthy and keep the spirit of learning online in this lesson we discuss basic competency 3.1.4 osmotic pressure of solutions or its application in everyday life osmotic pressure of solutions for example in making salted eggs making candied fruit the use of IVs by patients then the definition of osmotic pressure is the hydrostatic pressure resulting from the osmosis process osmotic pressure or osmotic pressure can be interpreted as the pressure exerted by solute molecules that prevent the movement of solvent molecules from the concentration area yes too low to the concentration area of the solute Hi across a semipermeable membrane while the osmosis event itself is the process of seeping liquid from a more dilute hypotonic solution to a more concentrated hypertonic solution or from a pure solvent to a solution through a semipermeable membrane note that there are two types of hypotonic and hypertonic solutions that are limited by a semipermeable membrane then the solvent will move or move from the dilute hypotonic solution to the concentrated hypertonic solution then another application of the application of the law of pressure apply osmotic pressure that can be observed in dialysis process in patients suffering from kidney failure this dialysis process uses the principle of osmotic pressure with the dialysis method, namely the process of transferring small molecules such as urea through semipermeable and other fluid input is then removed then reverse osmosis for example there is seawater desalination, namely processing seawater into fresh water calculation of osmotic pressure or V PV = NRT because osmotic pressure = V then for nonelectrolyte solutions V = npv RT or MRT While for electrolyte solutions C = MRT how is the osmotic pressure in the atmosphere m concentration of the solution in molarity er gas constant = 0.008 two interact mosfets per mole Kelvin absolute resume in Kelvin instructor fun hop next understanding of the hypertonic isotonic hypothesis you can read it yourself later then the first example of a person who is definitely not a glucose infusion solution if the molarity of the liquid is 3.5 three moles at a temperature of 37° Celsius Determine the osmotic pressure solution know m = 0.3 molar t = 37 degrees Celsius plus 273 = 310 Kelvin R = 0.008 2 liters of atmosphere per mole calcium is asked Answer pay attention because iron the property of the solution is non-electrolyte, namely glucose infusion, then V = Mr T = 0.30 times 0.082 times 310 = 7.6 26 atmospheres then the next question is the osmotic pressure of human blood at a temperature of 37° Celsius is 7.7 atmospheres If someone needs an infusion of NaCl solution Determine the mass of NaCl that must be dissolved in 1 l of solution at a temperature of 37° Celsius so that it is isotonic with human blood, it is immediately known that free blood or blood osmotic pressure = 7.7 atmospheres t = 37 degrees Celsius 310 Kelvin volume of solution 1 l = 1900s NaCl is isotonic with human blood NaCl = B blood because the solution is a strong electrolyte, then Alpha is almost or is considered the same as the pocket asked how many grams of NaCl mass answer the blood = V NaCl then = 7.7 atmospheres is the same as MRT i747 atmospheres times m mass five 8.5 grams per mole Hi times 0.082 Ali 310 times2 then m = 8.8 6 grams so the mass of NaCl which must be dissolved = 8.85 6 grams then the practice questions that you have to do in this notebook, then collect them after 1. chapter is finished, there are shortcomings. I apologize, that's all. Wassalamualaikum warahmatullahi wabarakatuh
