$A$ molar solution is one that contains one mole of a solute in

$3.0$ molal $NaOH$ solution has a density of $1.110 \ g/mL$. The molarity of the solution is :-

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 $NaCl = 58.5 \, g/mol$)

The molarity of $20\% \,(W/W)$ solution of sulphuric acid is $2.55 \, M$. The density of the solution is $........... \, g \, cm^{-3}$.

What is the weight to volume $ppm$ of $0.05 \% w/v$ $CaCl_2$ aqueous solution?

If $98 \, mg$ of $H_2SO_4$ is present in $100 \, g$ of solution,what is the molarity of the solution? (Given: density of solution = $1.25 \, g/mL$)
