Calculate the molarity of $NaOH$ solution prepared by dissolving $0.4 \ g$ of $NaOH$ in enough water to form $500 \ mL$ of the solution. (in $M$)

Molar solution means $1 \text{ mole}$ of solute present in

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

What is the density (in $g \ mL^{-1}$) of a $29\%$ (by mass) $H_2SO_4$ solution that has a molarity of $3.60 \ M$? (Molar mass of $H_2SO_4 = 98 \ g \ mol^{-1}$)

Calculate the molality of $1 \ L$ solution of $93 \ \%$ $H_2SO_4$ (weight/volume). The density of the solution is $1.84 \ g/mL$.

$200 \ g$ of $20 \% \text{ } w/w$ urea solution is mixed with $400 \ g$ of $40 \% \text{ } w/w$ urea solution. What is the weight percentage $(w/w \%)$ of the resultant solution (in $.33$)?
