A 3.0% (m/v) potassium chloride solution has a volume of 25.0 mL. How many moles of potassium chloride are in the sample?

Oduvanchick [21]

Using your knowledge of m/v = g/mL, you can start by putting that in the equation as:

$\frac{3g}{100mL}$

And you know that the volume is 25 mL. So you could put this into the equation as:

$\frac{25mL}{1}$

And you also know that the molar mass of KCl is 74.55g (K = 39.1 g/mol and Cl = 35.45 g/mol. Add them together to get 74.55g/mol).

We can then put this in the equation as:

$\frac{1mol}{74.55g}$

Then, we can mulitply them all together:

$\frac{3g}{100mL}* \frac{25mL}{1} * \frac{1mol}{74.55g}=0.01 mol$

And now we know that there are 0.01 moles of KCl in the sample.

A nursing instructor is describing the use of a head-to-toe approach for a comprehensive health assessment and how body systems

VladimirAG [237]

Answer:

A, C, D and E

Explanation:

In the assessment of legs, there are many systems that are combined for that part of the body to function optimally.

The reason that all the options are relevant in this question (except for B) specifically referring to legs, is that option B (the cardiovascular system) is not a main indicator of a problem with that part of the body specifically.

If something is wrong with the leg of a patient, there is a small likelihood of it being related to the cardiovascular system, because if the cardiovascular system is causing something to be wrong in the legs, it should not be limited to that section of the body. Hence, the other options are correct, but not option B.
