$A$ $1$ molal solution is defined as $1$ mole of solute dissolved in:

The molarity of urea (molar mass $60 \ g \ mol^{-1}$) solution obtained by dissolving $15 \ g$ of urea in $500 \ cm^3$ of water is

Two solutions of a substance are mixed as follows: $480 \ mL$ of $1.5 \ M$ first solution + $520 \ mL$ of $1.2 \ M$ second solution. The molarity of the final solution will be ............. $M$.
