You would expect snow to fail at the peak or the top because the weather is coldest there.
I would choose organ system
The molarity of a solution : 0.4 M
<h3>Further explanation</h3>
Given
0.2 moles of Potassium Oxide
500 ml of water = 0.5 L
Required
The molarity
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution

Assume volume of solution = volume of water(addition of solution volume from volume Potassium Oxide is negligible
Input the value :
M = 0.2 : 0.5
M = 0.4
Because the inner course is a totally different thing then the outer course
582 ml is the volume of gas.
Answer:
Explanation:
Using the ideal law of gases, the kinetic theory of gas can be stated as
PV = nRT
Here P is the pressure and it is given as 1.2 atm, V is the volume, which we need to find. Then R is the gas constant and T is the temperature while n is the concentration present.
As per the give question, P = 1.2 atm, T = 140 K and n = 0.5 moles, R = 8.314
V = 
V = 
So 582 ml is the volume of gas.
