The question, as presented, is incomplete. The entire question is shown below:

"<span>The density of a 13.2 mass % solution of NaF is 1.21 g/mL. Find the molarity of the solution."

We are asked to find the molarity of this solution, and molarity is defined as the amount of moles of a compound per unit volume, typically in units of mol/L.

The density of the NaF solution is 1.21 g/mL. Let's take a 1 L sample of this solution and determine the mass.

1.21 g/mL x 1000 mL = 1210 g of solution.

We are told that this solution is 13.2% NaF by mass. So the mass of NaF in this solution is:

1210 x 0.132 = 160 g NaF

We can then turn this mass of NaF into moles of NaF using the molecular weight of 42 g/mol.

160 g NaF / 42 g/mol = 3.80 moles NaF.

Now to convert this into molarity, we simply divide the amount of moles by the volume of sample, in this case 1L:

3.80 moles NaF/ 1L = 3.80 mol/L NaF or 3.80 M NaF.

The molarity is 3.80 M NaF.</span>

Summarize the relationship between an electron's energy level and its location in an atom
FromTheMoon [43]

Answer:

The further an electron is from the nucleus. the greater its energy level.

Explanation:

When an electron is close to the nucleus, it is at as low an energy level as it can get.

We must put energy into an electron to pull it away from the attraction of a nucleus.

So, electrons that are further from the nucleus are at higher energy levels.
