If the colored spheres are solutes, the overall direction of water would be out of the cell based on the principle of osmosis.

<h3>What is osmosis</h3>

It is the movement of water molecules from the region of high water potential (low solutes) to the region of low water potential (high solute) through a selectively permeable membrane.

In the illustration, there are more colored spheres outside of the cell than inside of it. This means that there are more solutes outside the cell (lower water potential) than inside of the cell (higher water potential).

Thus, water will move from the inside of the cell to the outside until an equilibrium is established.

To prepare 250mL of calcium chloride solution with a molar concentration of 1.20mol/L, what mass of calcium chloride would be re
e-lub [12.9K]

Answer:

33.30 grams of CaCl2 will be required

Explanation:

Given,

Volume of solution, V= 250 ml

Molarity of solution, M= 1.20 mol/L

Molecular mass of CaCL2, S= 40+(35.5 X 2)= 111

We know,

Required mass, W= SVM/1000

Now,

W = (111 X 250 X 1.20)/1000

    = 33300/1000

    = 33.30

Therefore, 33.30 grams of Calcium Chloride will be required.

If the temperature of a gas is raised from 30°C to 60°C, what happens to the pressure?
Fofino [41]
<h3>Answer:</h3>

The pressure increases by 10% of the original pressure

Thus the new pressure is 1.1 times the original pressure.

<h3>Explanation:</h3>

We are given;

  • Initial temperature as 30°C, but K = °C + 273.15
  • Thus, Initial temperature, T1 =303.15 K
  • Final temperature, T2 is 333.15 K

We are required to state what happens to the pressure;

  • We are going to base our arguments to Pressure law;
  • According to pressure law, the pressure of a gas and its temperature are directly proportional at a constant volume
  • That is; P α T
  • Therefore, at varying pressure and temperature

\frac{P1}{T1}=\frac{P2}{T2}

Assuming the initial pressure, P1 is P

Rearranging the formula;

[tex]P2=\frac{P1T2}{T1}[/tex]

P2=\frac{(P)(333.15K)}{303.15K}

     P2 = 1.099P

                 = 1.10 P

The new pressure becomes 1.10P

This means the pressure has increased by 10%

We can conclude that, the new pressure will be 1.1 times the original pressure.
