$171 \ g$ of cane sugar $(C_{12}H_{22}O_{11})$ is dissolved in $1 \ L$ of water. The molarity of the solution is ......... $M$.

The molality of $90\%$ ${H_2SO_4}$ solution is [density $= 1.8 \ g/mL$].

The molality of a solution containing $15.20 \ g$ of urea (molar mass = $60 \ g \ mol^{-1}$) dissolved in $150 \ g$ of water is:

Which of the following factors affect the molarity of a solution?

$A$ sample of drinking water is found to be severely contaminated with chloroform $(CHCl_3)$,which is a suspected carcinogen. The level of contamination is $15 \ ppm$ (by mass). Calculate the molarity of chloroform in the water sample.

The density of $3 \ M$ solution of $NaCl$ is $1.0 \ g \ mL^{-1}$. Molality of the solution is $...... \times 10^{-2} \ m$. (Nearest integer). Given: Molar mass of $Na$ and $Cl$ is $23$ and $35.5 \ g \ mol^{-1}$ respectively.
