The normality of $10 \%$ (weight/volume) acetic acid is ......... $N$.

At $T \ (K)$,$100 \ g$ of $98\%$ $H_2SO_4$ $(w/w)$ aqueous solution is mixed with $100 \ g$ of $49\%$ $H_2SO_4$ $(w/w)$ aqueous solution. What is the mole fraction of $H_2SO_4$ in the resultant solution?
(Given: Atomic mass $H = 1 \ u; S = 32 \ u; O = 16 \ u$)
(Assume that temperature after mixing remains constant)

If the density of a $2 \ M$ solution of ethylene glycol in water is $1.11 \ g/mL$, the molality (in $m$) of the solution is approximately

Explain $\% \, w/V$ and $\% \, w/w$ in brief.

What is the relation between molality $(m)$ of the solution and molar mass $(M_2)$ of the solute,where $W_2$ is the mass of solute in grams and $W_1$ is the mass of solvent in grams?

The density of liquid $HCl$ is $1.17 \ g/cm^3$. What is its molarity?
