<h3>What is concentration?</h3>
- Concentration in chemistry is calculated by dividing a constituent's abundance by the mixture's total volume.
- Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description.
- Any type of chemical mixture can be referred to by the term "concentration," however solutes and solvents in solutions are most usually mentioned.
- There are different types of molar (quantity) concentration, including normal concentration and osmotic concentration.
<h3>How is concentration determined?</h3>
- Subtract the solute's mass from the total volume of the solution. Using m as the solute's mass and V as the total volume of the solution, write out the equation C = m/V.
- To get the concentration of your solution, divide the mass and volume figures you discovered and plug them in.

The correct answer is the fourth option. The complete dissociation of a strong base is BOH + h20 -> B+ + OH- + H20 since this is the only base from the choices given. A base is a substance that accepts hydrogen ions.

Cell Membrane
The thin, flexible outer covering of a cell. It controls what enters and leaves a cell.
Explanation:
Answer:
0.488atm = Pressure Kr
Explanation:
The total pressure in a mixture of gases could be defined as the sum of the partial pressures of a mixture. For the mixture of gases in the problem:
Total pressure = Pressure He + Pressure Ar + Pressure Ne + Pressure Xe + Pressure Kr
Converting the total pressure to atm:
1252.5mm Hg * (1atm / 760 mmHg) = 1.648 atm
Replacing:
1.648atm = 0.32atm + 0.21atm + 0.44atm + 0.19atm + Pressure Kr
<h3>0.488atm = Pressure Kr</h3>
