Odisha Board Solutions for Chapter: Solutions, Exercise 1: QUESTIONS

Write down the equation that will show the relationship between normality and molarity.

Four solutions $\mathrm{A}, \mathrm{B}, \mathrm{C},$ and $\mathrm{D}$ contain $1 \mathrm{g}$ each of $\mathrm{HCl}, {\mathrm{HNO}}_3, {\mathrm{H}}_2{\mathrm{SO}}_4,$ and ${\mathrm{H}}_3{\mathrm{PO}}_4$ respectively per $100 \mathrm{mL}$. Arrange the solutions in the increasing order of their molarity and normality

Calculate the molarity when $73 \mathrm{g}$ of $\mathrm{HCl}$ is dissolved in water to make $1500 \mathrm{mL}$ solution.

Calculate the molarity of seminormal ${\mathrm{Na}}_2{\mathrm{CO}}_3$ solution. $\mathrm{Na}=23, \mathrm{C}=12$

$5.85 \mathrm{g}$ of $\mathrm{NaCl}$ is dissolved in $90 \mathrm{g}$ water. What is the mole fraction of $\mathrm{NaCl}$?

What is the molality of a solution containing $0.25$ mole of the solute in $250 \mathrm{g}$ of the solvent?

Sp. gr of $\mathrm{HCl}$ solution is $1.17$. $100 \mathrm{g}$ of $\mathrm{HCl}$ solution contains $36.5 \mathrm{g}$ of acid. Calculate the normality of the solution.

$200 \mathrm{mL}$ of $0.2 \mathrm{M} \mathrm{NaOH}$ and $300 \mathrm{mL}$ of $0.3 \mathrm{M} \mathrm{NaOH}$ are mixed. Find out the molarity of the resulting solution.
