The osmotic pressure, π, of a solution of glucose is 83.1 atm . find the molarity of the solution at 298 k. express the molarity to three significant figures and include the appropriate units.

Molarity for this solution is: 3.40 mol/L

Explanation:

Osmotic pressure is the colligative property which formula is:

π = M . R . T

83.1 atm = M . 0.082 L.atm/mol.K . 298K

83.1 atm / (0.082 L.atm/mol.K . 298K) = M

As you see all the units are cancelled, except for mol/L which means certainly Molarity

83.1 atm / (0.082 L.atm/mol.K . 298K) = 3.40 mol/L

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
