(I posted the picture for a ray diagram and the first law of reflection.) The rays show the first law of reflection since everything gets reflected. Look at the picture for more:
The nonvolatile, nonelectrolyte cholesterol, C27H46O (386.60 g/mol), is soluble in benzene C6H6. Calculate the osmotic pressure
generated when 14.6 grams of cholesterol are dissolved in 263 ml of a benzene solution at 298 K. The molarity of the solution is M. The osmotic pressure of the solution is atmospheres.
1 answer:
Answer:
Explanation:the formula for osmotic pressure is given in the first line, all the terms are explained before solution, from the question,
Molar mass=Mm=386.6
Mass= m= 14.6
Volume= 263/1000 = 0.263dm^3
Temperature=T= 298K.
Gas constant .R= 0.082
Then substitute into the equation πV= nRT
Making π subject of formula
π= nRT/V
Then further substitution
