Before determining the osmolarity of a solution we need to figure out its molarity first. Now before we calculate molarity we need to understand the following ideas. We must know that 1 Gram-Molecular weight of a compound is its molecular wt. expressed in grams and that 1 Gm.-Mol. Wt. =...
(4)weight percent(wt %)=weight of soluteweight of solution ×100% To convert from volume percent to weight percent, or to find the weight of solute in a given volume of solution of a known weight percent, the density of the solution, usually expressed in grams per milli...
from Chapter 13 / Lesson 2 61K Learn the dilute and concentrated solution definition. Compare and contrast dilute vs concentrated solution examples and see how a solution changes physically and chemically as it goes from dilute to concentrate. Related to this QuestionHow...

we need to do the conversion of a mass of a given solute to its molar number in order to give the molar concentration. To do this, we need to divide the mass by themolecular weightof the solute. For example, if we want to prepare a 1 M of potassium sulfate solution, 174.26 g mol...
What is molarity? What is molality? Compare molarity vs molality by viewing molality and molarity formulas, how to calculate molarity and molality,...
How many grams of NaCI (molecular weight = 58.5 g/mol) would you dissolve in water to make a 0.5 M NaCl solution with a final volume of 500 mL? What is the molarity of a solution containing 23 g of NaCl in 500 mL of solution? (the...
