Explanation:
Molarity is concentration measured in moles per liters. It is the number of moles of solute per liters of solution. The formula is:

We know the solution of HCl has a molarity of 0.5 molar and there are 0.8 liters of solution.
- 1 molar (M) is equal to 1 mole per liter.
- Let's convert the molarity of 0.5 M HCl to 0.5 mol HCl per liter. This will make unit cancellation easier.
The moles of solute or HCl are unknown, so we can use x. Now, we can substitute all known values into the formula.

Since we are solving for the moles of solute (x), we must isolate the variable. It is being divided by 0.8 liters. The inverse of division is multiplication, so we multiply both sides by 0.8 L.


The units of liters (L) cancel.


This solution contains <u>0.4 moles of HCl.</u>

Before Hybridization => C: 1s²<u> ⇵</u> 2s²<u>⇵</u> 2p₋₁<u>↑</u> 2p₀<u>↑</u> 2p₊₁<u>∅</u>
After Hybridization => C: 1s² 2sp¹ 2sp¹ 2p₀¹2p₊₁¹ => 2 hybrid orbitals and 2 unhybridized p-orbitals at the n=2 energy level.
<span>Mitochondria take energy and convert it to ATP. This is the transferred into the cells for it to be used by the rest of the organelles. ATP, along with ADP, are the main sources of energy that organelles use as a way of carrying out their specific functions.</span>
One way is for <span>a landowner to gather as much information as possible about his or her private water well, to know how it works, as well as who has had the land before them. The landowner needs to see if anyone has used pesticides in the area, as it can contaminate the well water. This is the most common way. The landowner can also check to see if any other chemicals have been spilt in the area or even a gas or oil leak, as that too can cause the contamination of well water.
I hope this helps.</span>
