$A$ solution of chloroform in nitrogen is an example of:

When $100 \ mL$ of $2 \ M \ KCl$ and $200 \ mL$ of $3 \ M \ K_2SO_4$ solutions are mixed,what will be the molarity of $K^+$ ions in the resulting mixture (in $M$)?

When $W_B \ g$ of solute (molecular mass $M_B$) is dissolved in $W_A \ g$ of solvent,the molality $m$ of the solution is:

How many grams of $CH_3OH$ should be added to water to prepare $150 \ mL$ solution of $2 \ M \ CH_3OH$?

$3.0$ molal $NaOH$ solution has a density of $1.110 \ g/mL$. The molarity of the solution is :-

The volume of water which must be added to $40 \ cc$ of $0.25 \ M$ oxalic acid solution to make it exactly decimolar $(0.1 \ M)$ is $....... \ cc$.
