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?

The molarity of the solution obtained by mixing $480 \, mL$ of $1.5 \, M$ solution with $500 \, mL$ of $1.2 \, M$ solution is ........ $M$.

Which of the following concentration terms does not change with a change in temperature?

Calculate the mole fraction of solute in the solution if the solution is prepared by dissolving $394 \ g$ of a nonvolatile solute in $622 \ g$ of water at $30^{\circ}C$ (Molar mass of solute $= 342 \ g \ mol^{-1}$).

Commercially available $H_2SO_4$ is $98 \ g$ by weight of $H_2SO_4$ and $2 \ g$ by weight of water. Its density is $1.38 \ g \ cm^{-3}$. Calculate the molality $(m)$ of $H_2SO_4$ (molar mass of $H_2SO_4$ is $98 \ g \ mol^{-1}$). (in $m$)

The molality of an aqueous solution of glucose is $1.0 \ m$. The mole fraction of glucose is approximately .....
