If a solution is $98\% \ H_2SO_4$ by weight and has a density of $1.8 \ g/mL$,its molarity is ....... $M$.

Explain the types of solutions based on the physical states of solute and solvent with suitable examples.

The volumes of two $HCl$ solutions $A$ $(0.5 \, M)$ and $B$ $(0.1 \, M)$ to be mixed for preparing $2 \, L$ of $0.2 \, M \, HCl$ are

State whether the following sentences are true $(T)$ or false $(F)$.
