How many grams of $NaOH$ must be dissolved in $500 \, g$ of solution to obtain a $10 \% \, w/w$ concentration?

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

The molarity of the solution obtained by mixing $50 \ mL$ of concentrated $H_2SO_4$ $(36 \ N)$ with $50 \ mL$ of water is .......... $M$.

What is the concentration of nitrate ions if equal volumes of $0.1 \, M$ $AgNO_3$ and $0.1 \, M$ $NaCl$ are mixed together (in $, M$)?

Calculate the molarity if $30 \, mL$ of $0.5 \, M$ $H_2SO_4$ is diluted to $500 \, mL$. (in $, M$)

$100 \ g$ of solute is dissolved in $1400 \ g$ of solvent. The density of the resultant solution is $1.5 \ g/mL$. The ratio of its molarity $(M)$ to molality $(m)$ is:
