What will be the normality of a $1 \ L$ solution of $5 \ M$ $H_2SO_4$ after diluting it to $10 \ L$ by adding water (in $N$)?

To $5.85 \, g$ of $NaCl$,$1 \, kg$ of water is added to prepare a solution. What is the strength of $NaCl$ in this solution? (Molecular weight of $NaCl = 58.5 \, g/mol$)

In one molal solution that contains $0.5 \ mol$ of a solute,there is

The density of a solution prepared by dissolving $120 \ g$ of urea (mol. mass $= 60 \ u$) in $1000 \ g$ of water is $1.15 \ g/mL$. The molarity of this solution is : ............ $M$

The amount of water that should be added to $500 \, mL$ of $0.5 \, N$ solution of $NaOH$ to give a concentration of $10 \, mg$ per $mL$ is (in $, mL$)

Find the molarity of the $5$ molal urea solution,whose density is $1.3 \ g / mL$ (given,molecular weight of urea is $60.06 \ g / mol$).
