$500 \mathrm{mL}$ of $1 \mathrm{M}$ solution of glucose is mixed with $500 \mathrm{mL}$ of $1 \mathrm{M}$ solution of glucose. The final molarity of the solution will be:

The molality of a sulphuric acid solution is $0.2$. Calculate the total weight of the solution having $1000 \mathrm{g}$ of solvent.

What volumes should you mix $0.2 \mathrm{M} \mathrm{NaCl}$ and $0.1 \mathrm{M}$ ${\mathrm{CaCl}}_2$ solutions so that in the resulting solution the concentration of positive ion is $40\%$ lesser than concentration of negative ion. Assume total volume of solution as $1000 \mathrm{ml}$.

$100 \mathrm{mL}$ of $0.8 \mathrm{M} \mathrm{NaOH}$ is used to neutralise $100 \mathrm{mL}$ of the solution obtained by passing $2.70 \mathrm{g} {\mathrm{SO}}_2{\mathrm{Cl}}_2$ in water. Select the correct statement:

Which ones are correct about the solution that contains $3.42$ $ppm{Al}_2{\left({SO}_4\right)}_3$ and $1.42 \mathrm{ppm}$ ${\mathrm{Na}}_2{\mathrm{SO}}_4?$

Which of the following graphs correctly represents the variations?

Which of the following concentration is correct for $13$ mass percent of sulphuric acid (density: $1.09 \mathrm{g} {\mathrm{mL}}^{-1}$)?

$1 \mathrm{mole} {\mathrm{BaF}}_2+\underset{\mathrm{Resulting} \mathrm{mixture}}{1 \mathrm{mole} {\mathrm{H}}_2{\mathrm{SO}}_4\underset{}{\to }}$ will be neutralized by:
