You note that cells placed in a solution crenate. What could you definitively conclude about the solution?
lys-0071 [83]

Answer:it means the cell is an hypertonic or high concentration solution

Explanation: osmosis is defined as movement of water from a region of high concentration to a region of low concentration of water.

Now being in a hypertonic solution means the sorrounding solution in a high concentration of the solute which means water is in low in concentration , so osmotic pressure move water from the cell (which has a relatively higher water concentration )to it's sorrounding which has a lower concentration of water, resulting in the shrinking or crenation of the cells.

The volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

<h3>How to calculate volume?</h3>

The volume of a given gas can be calculated using the following Charle's law equation:

V1/T1 = V2/T2

Where;

  • T1 = initial temperature
  • T2 = final temperature
  • V1 = initial volume
  • V2 = final volume

  • V1 = 9L
  • V2 = ?
  • T1 = 325K
  • T2 = 450K

9/325 = V2/450

325V2 = 4050

V2 = 4050/325

V2 = 12.46L

Therefore, the volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.
