The molality of $90\%$ ${H_2SO_4}$ solution is [density $= 1.8 \ g/mL$].

$1 \, M$ solution contains

What is the molarity of a $1 \ L$ solution of $93\% \ (w/v)$ $H_2SO_4$ (in $M$)? The density of the solution is $1.84 \ g/mL$.

When $7.1 \ g$ of $Na_2SO_4$ (molecular mass $142$) dissolves in $100 \ mL$ of $H_2O$,the molarity of the solution is $.........$ $M$.

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 $H_2SO_4 = 98 \ g \ mol^{-1}$)

If $22 \ g$ of benzene $(C_6H_6)$ is dissolved in $122 \ g$ of carbon tetrachloride $(CCl_4)$,calculate the mass percentage of benzene. (in $\%$)
