When $100 \ mL$ of $0.3 \ N$ $HCl$ solution is mixed with $200 \ mL$ of $0.6 \ N$ $H_2SO_4$ solution,what is the normality of $H_2SO_4$ in the final mixture?

What is the molarity of a solution containing $3.2 \ g$ of $NaOH$ (molar mass $40 \ g \ mol^{-1}$) in $250 \ cm^{3}$ of water?

Molarity $(M)$ of an aqueous solution containing $x \ g$ of anhydrous $CuSO_4$ in $500 \ mL$ solution at $32^{\circ} C$ is $2 \times 10^{-1} \ M$. Its molality will be. . . . . .$\times 10^{-3} \ m$ (nearest integer). [Given density of the solution $= 1.25 \ g/mL$.]

What volume (in $mL$) of $3.0 \ M \ H_2SO_4$ is required to prepare $1.0 \ L$ of a $1.0 \ M$ solution?

If $120 \, g$ of urea (molar mass = $60 \, g/mol$) is dissolved in $1000 \, g$ of water and the density of the resulting solution is $1.15 \, g/mL$,what is the molarity of the solution in $M$?
