The molarity of the solution when $4.9 \ g$ of $H_2SO_4$ is dissolved in $250 \ mL$ of solution is: (in $M$)

An aqueous solution of glucose is $10 \%$ in strength. The volume in which $1 \, g-mole$ of it is dissolved will be ............. $L$.

What is the meaning of concentration of a solution? Discuss the different ways to express the concentration of solutions.

$450 \ mg$ of glucose is dissolved in $100 \ g$ of solvent. What is the molality of the solution (in $m$)?

What is the approximate molality of $10 \% (w/w)$ aqueous glucose solution (in $m$)? (Molar mass of glucose $= 180 \ g \ mol^{-1}$)

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 $C=12, H=1, O=16 \ u$)
