Answer:

#"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........#((1000*g)/(18.01*g*mol^-1))/(1*L)=55.52*mol*L^-1#...most of the time we deal with concentrations much lower than this....

If we take a #36.46*g# mass of #HCl#, and dissolve it in #1*L# of water, we have a concentration of.........

#((36.46*g)/(36.46*g*mol^-1))/(1.00*L)=1.00*mol*L^-1# WITH RESPECT TO #HCl#...........
