order of increasing  concentration

Solution

Molarity shows the number of moles of solute in every 1 liter of solution.

[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]

Solution A : 0.5 moles : 2 L solution = 0.25 M

Solution B : 1 moles : 3 L solution = 0.33 M

Solution C : 1.5 moles : 4 L solution = 0.375 M
