What is the concentration of pure water? And what is the concentration of HCl if a 36.46*g mass of the gas is dissolved in a 1*L volume of aqueous solution?

$\text{Molar concentration"="Moles of solute"/"Volume of solution}$

Explanation:

And we can even quote a concentration for water, and find out that its molar concentration, as defined, is VERY high..........

We gots........$\frac{\frac{1000 \cdot g}{18.01 \cdot g \cdot m o {l}^{-} 1}}{1 \cdot L} = 55.52 \cdot m o l \cdot {L}^{-} 1$...most of the time we deal with concentrations much lower than this....

If we take a $36.46 \cdot g$ mass of $H C l$, and dissolve it in $1 \cdot L$ of water, we have a concentration of.........

$\frac{\frac{36.46 \cdot g}{36.46 \cdot g \cdot m o {l}^{-} 1}}{1.00 \cdot L} = 1.00 \cdot m o l \cdot {L}^{-} 1$ WITH RESPECT TO $H C l$...........
