Consider two isotonic solutions at same temperatures. The solute in the solution A has the molecular mass M and the solute in the solution B has the molecular mass 2M. If the volume of both the solution is same; then, which of the following statements is correct?
The number of the moles of solutes in A and B are same.
The mass of the solute in A and B is same.
The number of the moles in solution A is double the number of the moles in solution B.
The number of the moles in solution B is double the number of the moles in solution A.

what is filteration? please, answer it fast
What is Collioidal?
whitch is the biggest molecule
In our school, we have been taught chemical equation,their reaction,formulaes ,element name,their Laten name,their symbols and their valancy.So how can I get these by Meritnation.Please help.
