The solution in which the blood cells retain their normal form is with regard to the blood:

If a $6.84\% \ (w/v)$ solution of sucrose (molar mass $342 \ g/mol$) is isotonic with a $1.52\% \ (w/v)$ solution of thiocarbamide,what is the molar mass of thiocarbamide?

Isotonic solutions have the same

In osmosis:

Which of the following colligative properties is most suitable for determining the molar mass of polymers?

$A$ solution is made by dissolving $20 \ g$ of a substance in $500 \ mL$ of water. Its osmotic pressure was found to be $600 \ mm$ of $Hg$ at $15 \ ^oC$. The molecular weight of the substance is
