Mole percent is the percentage of the total moles that is of a particular component.
- Separated by an actual physical barrier
<span>- Geographic isolation can be overcome in some circumstances but the majority of the population will be isolated and therefore will diverge into different species

Answer:
Option ( 1 )
Explanation:
This atom has a cub close pack structure, and therefore - the number of edge center present in X atoms = 4,
Number of unit cells present in X atoms = 6
____________________________________________________
Now the 6th coordination number of X atom = 6 * 4 = 24,
So respectively, the 3rd coordination number of X = 8 -
And thus the ratio between the 6th coordination number and the 3rd coordination number = 24 / 8 = 3,

Answer:
1.68L
Explanation:
Step 1:
Data obtained from the question. This includes the following:
Initial Molarity (Mi) = 7M
Initial volume (Vi) 0.6L
Final Molarity (Mf) = 2.5M
Final Volume (Vf) =.?
Step 2:
Determination of the final volume of the solution.
This can be achieved as shown below:
MiVi = MfVf
Divide both side by Mf
Vf = MiVi /Mf
Vf = 7 x 0.6 / 2.5
Vf = 1.68L
Therefore, the new volume of the solution is 1.68L
You omitted what it was raised to the power in 1.3 x 10's gallons of water, so i will put it up as 1.3 x 10^15 gallons of water and solve with it
Answer:1,083,333 days
Explanation:
Total amount of water held by lake Michigan= 1.3 x 10^15 gallons of water
Amount of water Chicago uses per day =Chicago uses 1.2 x 10^9 gallons of water /day
Therefore,
Number of days water would last if it doesnt rain = Total gallons provided by lake Michigan/ Total gallons consumed per day
=1.3 x 10^15 gallons of water/ 1.2 x 10^9 gallons of water /day
= 1,083,333 days
