Question

Beaker a contains 6 liters of water and 1 osmole of glucose. beaker b contains 10 liters of water and 2 osmoles of glucose. which one has the greater osmolarity and by how much?

a) beaker a is 6 osm/l and breaker b is 5 osm/l. beaker a has the greater osmolarity by 1 osm/l

b) beaker a is 0.16 osm/l and beaker b is 0.2 osm/l. beaker b has the greater osmolarity by 0.04 osm/l

c) beaker a is 0.2 osm/l and beaker b is 0.16 osm/l. beaker a has the greater osmolarity by 0.04 osm/l

d) beaker a is 5 osm/l and beaker b is 6 osm/l. beaker b has the greater osm/l by 1 osm/l

Answer 1

Beaker A has the greater osmolarity by 0.04 osm/l compared to Beaker B.

Step-by-step explanation:

The greater the concentration of solutes in a solution, the greater its osmolarity. In Beaker A, there is 1 osmole of glucose dissolved in 6 liters of water, giving it an osmolarity of 1 osmole/liter. In Beaker B, there are 2 osmoles of glucose dissolved in 10 liters of water, giving it an osmolarity of 0.2 osmoles/liter. Therefore, Beaker A has the greater osmolarity by 0.04 osm/l. The correct answer is c) Beaker A is 0.2 osm/l and Beaker B is 0.16 osm/l. Beaker A has the greater osmolarity by 0.04 osm/l.

Answer 2

Beaker B has the higher osmolarity of 0.2 osm/l compared to beaker A's 0.16 osm/l. The difference in osmolarity between the two is 0.04 osm/l.

Step-by-step explanation:

The osmolarity of a solution is defined by the number of osmoles of solute per liter of solution. To find the osmolarity of each beaker, we simply divide the number of osmoles by the volume in liters of each beaker.

For beaker A, with 1 osmole of glucose in 6 liters of water, the osmolarity is 0.166 osm/l (rounded to three decimal places).

For beaker B, with 2 osmoles of glucose in 10 liters of water, the osmolarity is 0.200 osm/l (rounded to three decimal places).

Therefore, beaker B has the greater osmolarity by 0.034 osm/l (0.200 - 0.166), so the correct answer is option B: beaker a is 0.16 osm/l and beaker b is 0.2 osm/l. Beaker B has the greater osmolarity by 0.04 osm/l.
