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

When $5 \ g$ of acetic acid is dissolved in $1 \ L$ of ethanol,assuming no reaction occurs between them,calculate the molality of the resulting solution. (Density of ethanol = $0.789 \ g/mL$) (in $m$)

The number of units,which are used to express the concentration of solutions from the following,is $.......$ Mass percent,Mole,Mole fraction,Molarity,ppm,Molality.

The density of a nitric acid solution is $1.5 \ g \ mL^{-1}$. Its weight percentage is $68 \%$. What is the approximate concentration (in $mol \ L^{-1}$) of nitric acid? $(N=14 \ u, O=16 \ u, H=1 \ u)$

The $ppm$ level of $F^{-}$ in a $500 \ g$ sample of a toothpaste containing $0.2 \ g$ $F^{-}$ is:

What volume (in $mL$) of $3.0 \ M \ H_2SO_4$ is required to prepare $1.0 \ L$ of a $1.0 \ M$ solution?
