UPLOAD PHOTO AND GET THE ANSWER NOW! Solution : `"Molarity"=("Moles of the solute")/("Volume of solution in L")=(5.85//58.5)/(0.500L)="0.2 mol L"^(-1)`.
What will be the molarity of a solution?Definition: Molarity of a given solution is defined as the total number of moles of solute per litre of solution.
Which of the following solutions have the same concentration?<br> Reason: Solution which have the same osmotic pressure at the same temperature are known as isotonic solutions.
