Dissolving $120 \ g$ of a compound (mol. wt $= 60$) in $1000 \ g$ of water gave a solution of density $1.12 \ g \ mL^{-1}$. The molarity of the solution is: (in $M$)

In an aqueous glucose solution,the mole fraction of water is $40$ times the mole fraction of glucose. What is the weight percentage $(w/w)$ of glucose in the solution?

The amount of $NaOH$ in $g$ in $250\,cm^3$ of a $0.100\,M\,NaOH$ solution would be ........... $g$.

Density of $12.25\%$ (by weight) $H_2SO_4$ solution is $1.056 \ g/mL$. The molarity of the solution is .......... $M$.

If the concentration of glucose $(C_{6}H_{12}O_{6})$ in blood is $0.72 \ g \ L^{-1}$,the molarity of glucose in blood is $..... \times 10^{-3} \ M$. (Nearest integer)
(Given: Atomic mass of $C=12, H=1, O=16 \ u$)

The molar concentration of chloride ions in the resulting solution of $300 \ mL$ of $3.0 \ M$ $NaCl$ and $200 \ mL$ of $4.0 \ M$ $BaCl_{2}$ will be (in $M$)
