To prepare a solution of concentration $0.03 \ g/mL$ of $AgNO_3$,what amount of $AgNO_3$ should be added in $60 \ mL$ of solution?

$x \ g$ of $NaCl$ is added to water in a beaker with a lid. The temperature of the system is raised from $1^{\circ}C$ to $25^{\circ}C$. Which out of the following plots is best suited for the change in the molarity $(M)$ of the solution with respect to temperature? [Consider the solubility of $NaCl$ remains unchanged over the temperature range]

An $X$ molal solution of a compound in benzene has a mole fraction of solute equal to $0.2$. The value of $X$ is

$171 \ g$ of cane sugar $(C_{12}H_{22}O_{11})$ is dissolved in $1 \ L$ of water. The molarity of the solution is ......... $M$.

An aqueous solution contains $28\%$ by weight of a liquid $A$ $(m_w = 140)$. The mole fraction of liquid $A$ is:

The density of an aqueous solution of $4\%$ by mass $NaOH$ is $1.04\ g/mL$. The molality of the solution is:
