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

Which of the following is dependent on temperature $?$

The value of which of the following units of concentration will not change with the change in temperature?

An aqueous $KCl$ solution of density $1.20 \ g \ mL^{-1}$ has a molality of $3.30 \ mol \ kg^{-1}$. The molarity of the solution in $mol \ L^{-1}$ is ..... . (Nearest integer)
[Molar mass of $KCl = 74.5 \ g \ mol^{-1}$]

The mole fraction of a solute in a binary solution is $0.1$. At $298 \ K$, molarity of this solution is same as its molality. Density of this solution at $298 \ K$ is $2.0 \ g \ cm^{-3}$. The ratio of molecular weights of the solute and the solvent $(M_{solute} / M_{solvent})$ is:
