What is the mass percent of the solute in the solution obtained by dissolving $5 \mathrm{g}$ of the solute in $50 \mathrm{g}$ of water?

A sample of $\mathrm{NaOH}$weighing $0.40 \mathrm{g}$ is dissolved in water and the solution is made to $50.0 {\mathrm{cm}}^3$ in volumetric flask. What is the molarity of the resulting solution?

How many moles and how many grams of sodium chloride ($\mathrm{NaCl}$) are present in $250 {\mathrm{cm}}^3$ of a $0.500 \mathrm{M} \mathrm{NaCl}$ solution?

Concentrated aqueous sulphuric acid is $98 \%$ ${\mathrm{H}}_2{\mathrm{SO}}_4$by mass and has a density of $1.84 \mathrm{g} {\mathrm{cm}}^{-3}$. What volume of the concentrated acid is required to make $5.0 \mathrm{L}$ of $0.500 \mathrm{M}$ ${\mathrm{H}}_2{\mathrm{SO}}_4$solution?

How many grams of barium chloride (${\mathrm{BaCl}}_2$) are needed to prepare $100 {\mathrm{cm}}^3$ of $0.250 \mathrm{M}$ ${\mathrm{BaCl}}_2$ solution?

Note: the question is given as it is in the book.

How many moles and how many grams of sodium chloride ($\mathrm{NaCl}$) are present in $250 \mathrm{mL}$ of a $0.50 \mathrm{M}$ $\mathrm{NaCl}$ solution?

A sample of ${\mathrm{NaNO}}_3$weighing $0.38 \mathrm{g}$ is placed in a $50.0 \mathrm{mL}$ measuring flask. The flask is then filled with water up to the mark on the neck. What is the molarity of the solution?

In a reaction vessel, $0.184 \mathrm{g}$ of $\mathrm{NaOH}$is required to be added for completing the reaction. How many millilitres of $0.150 \mathrm{M} \mathrm{NaOH}$solution should be added for this requirement?
