Exam 5: Solution Concentration

Consider the two containers shown below separated by a seminpermeable membrane. When allowed to stand overnight, water will have moved from the right-hand container to the left hand container..

A solution is made by dissolving 22.5 mL of oil in enough gasoline to give 60.5 mL of solution. What is the % (v/v) of oil in the solution?

What is the molar mass of ibuprofen, C₁₃H₁₈O₂?

An oral rehydration solution contains 30 mEq/L of citrate^3-, what is the molarity of citrate in this solution?

The total molarity of an intravenous solution is given on the label as 151 mEq/L. The osmolarity of this solution is also 151 mEq/L.

Based on the following graph, approximately what minimum temperature would be needed to dissolved 20 g of this solute in 1.00 L of water?

The following equation can be used when C represents either a M or % (w/v) concentration.

Consider the two containers separated by a semipermeable membrane that allows both glucose and sucrose to pass through. Answer the following questions as appropriate with: right, left, or no movement. -Upon standing the water molecules will move in which direction?

Consider the two containers shown below separated by a seminpermeable membrane. When allowed to stand overnight, there will be no change in the liquid levels.

Which of the following is(are) an example(s) of a hypertonic intravenous solution? (NS represents normal saline.)

Dialysis and osmosis are used for the same purposes.

How would the following solution be classified? 0.05 M in KCl and 0.14 M in glucose

Consider two solutions, A and B, separated by a seminpermeable membrane that allows water and small molecules to pass through as shown below. Fill the blank(s) with the appropriate terms from the list below. right left osmosis dialysis -Solution A is 0.10 M in lactose and 0.050 M in urea. Solution B is 0.15 M in KCl. Water will flow to the ______________________compartment.

Consider two solutions, A and B, separated by a seminpermeable membrane that allows water and small molecules to pass through as shown below. Fill the blank(s) with the appropriate terms from the list below. right left osmosis dialysis -If the seminpermeable membrane has pores too small to allow glucose to pass through, ______________will not occur.

In cases of cerebral endema, a hypertonic solution is administered. The goal of giving the patient the hypertonic solution would be to pull fluid from the cells through the process of osmosis.

A solution contains 5.75 mg of magnesium ions in 332 mL of solution. What is the concentration of the solution in mEq/L?

If 1.00 mol of each of the following solutes is dissolved in 2.00 L of an aqueous solution, which solution contains the largest number of solute particles?

The %(v/v) of a solution can be defined as:

There is a 9 M aqueous HCl solution in the stock room, but a 5 M solution is required for an experiment. Doubling the volume of the 9 M sample with water will produce the 5 M solution.

The concentration of cholesterol in plasma was determined to be 215 mg/dL. The mass of cholesterol in 59.1 mL of this plasma is 127 mg.
