1. Molarity (M): moles of solute/liters of solution or moles/L (mol/L) 2. w/v (g/mL): weight in grams of solute/milliliters of solute 3. w/w: weight in grams of solute/weight in grams of solution (g/g) 4. v/v: volume of solute/volume of solution (L/L) Molar Mass ...
What is the molarityk and molality of a 13% solution (by weight) of sulphric acid with a density of 1.02mL−1? To what volume should 100mL of this acid be diluted in order to preapre a 1.5N solution? Video Solution Text SolutionVerified by Experts The correct Answer is:Molality=1.5...
To find the molarity and molality of a 13% solution (by weight) of sulfuric acid with a density of 1.02 g/mL, we will follow these steps: Step 1: Calculate Molarity 1. Understand the formula for molarity: Molarity (M)=Percentage by weight×10×Density (g/mL)Molecular weight (g/mol)...

In order to explain the fact that gases always appear to combine chemically in simple proportions by volume, Avogadro suggested that under the same conditions of temperature and pressure equal volumes of all gases contain the same number of molecules. If this be true it has the immediate conseque...

Total volume of the solution is 31.72L. Formula for dilution MiVi = MfVf For ammonium peroxide MiVi = MfVf (0.0745mol/L) X 0.32L = Mf X 31.72L Final molarity of NH4OH in the solution is 7.51X10^-4 mol/L. For hydrogen peroxide, MiVi = MfVf (0.131mol/L) X 1.21L = Mf X 31.72...
This determination is essential when the concentration should be given in molarity rather than in weight per volume. A discrepancy was noted between the number-average molecular weights of two lots of poloxamer 188. That difference is taken into account prior to the establishment of any comparison ...
