Answer 1

molarity is the no.of moles dissolved in one litre of solution

Answer 2

1) number of moles of a solute dissolved in one litre solution is called molarity of the solution.

2)concentration of solutions are generally expressed in molarity units.

3) example: one molar 1M sucrose solution means 342gms ( Molecular wt. of sucrose=342) dissolved in 1 litre solution (water).

4) Molarity =
$\frac{number \: of \: moles \: of \: solute}{volume \: of \: solution \: in \: litres}$
