The concentration of an aqueous solution of $0.01 \ M \ CH_3OH$ is very nearly equal to which of the following?

Two solutions labelled as $3 \, M \, HCl$ and $1 \, M \, HCl$ are mixed in the ratio of $x : y$ by volume and the molarity of the resulting solution is $1.5 \, M$. What is the molarity of the resulting solution if they are mixed in the ratio $y : x$ by volume?

An antifreeze solution is prepared from $222.6 \ g$ of ethylene glycol $(C_2H_6O_2)$ and $200 \ g$ of water. Calculate the molality of the solution. If the density of the solution is $1.072 \ g \ mL^{-1}$,then what shall be the molarity of the solution?
