Explanation:
has lost 1 electron. Therefore, a potassium ion has a smaller radius since it has less electrons.
The volume occupied by the given mol of helium gas at the given temperature and pressure is 91.6L.
The Ideal gas Law, also called the overall fuel equation, is the equation of kingdom of a hypothetical ideal gas. It is a superb approximation of the conduct of many gases below many situations, even though it has several limitations.
The precise gas regulation states that PV = NRT, wherein P is absolutely the pressure of a gasoline,volume V is the quantity it occupies, N is the quantity of atoms and molecules inside the fuel, and T is its absolute temperature.
Given;
Amount of helium n = 2.59 mole
Pressure p = 0.826 atm
Temperature T = 356 K
The volume of Helium = ?
PV = nRT
V = nRT/P
V = 2.59 mole * 0.826 atm * 356K/0.826
V = 75.6626/0.826
V = 91.6 L

Answer: The concentration of Silver Nitrate in solution # 4 is 3.5x10-6 M
Explanation:
When calculating the concentration of a dilute solution, we use the equation:
C1V1 = C2V2
Where C1 = concentration of the known solution
V1= amount of know solution
C2= new concentration
V2= capacity of the flask
Keep in mind that solution #2 is not related to the preparation of solutions #3 y #4, so the concentration of #2 is irrelevant.
For calculating the concentration of solution #4 , we first calculate the concentration of the solution #3, that comes from the solution #1.
- Calculating concentration solution #3
- C1V1 = C3V3
- C3= (0.0002442 M * 10mL) / 250mL
- C3= 9.8X10-6M
2. Calculating concentration solution #4
- C3V3 = C4V4
- C4= (9.8X10-6M *18mL) / 50mL
- C4= 3.5X10-6 M
It means there is a lot of the same thing and not many others
