The answer is B. Heart attack.

Your heart pumps blood so it can circulate to your tissues as well as get oxygen from your lungs. If your heart can't pump blood well you can feel short of breath. This can all happen when you are having a heart attack.

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.
