$A$ $5 \%$ solution of cane sugar (mol. wt. $= 342$) is isotonic with $1 \%$ solution of a substance $X$. The molecular weight of $X$ is

During osmosis,the flow of water through a semipermeable membrane is:

$A$ solution contains a non-volatile solute of molecular mass $M_p$. Which of the following can be used to calculate the molecular mass of the solute in terms of osmotic pressure ($m = \text{Mass of solute}$,$V = \text{Volume of solution}$,and $\pi = \text{Osmotic pressure}$)?

$18 \text{ g}$ of glucose (molar mass $= 180 \text{ g/mol}$) is dissolved in water to prepare $500 \text{ ml}$ solution at $15^{\circ}\text{C}$. Calculate the osmotic pressure of the solution. $[R = 0.0821 \text{ L atm K}^{-1} \text{ mol}^{-1}]$ (in $\text{ atm}$)

What does a semi-permeable membrane allow to pass through?
