How do you solve for mole fraction, density and %w/w, when you are given Cr_2(SO_4)_3, with molarity of 1.26 M and molality of 1.37 m? Calculate molality 6 M of H_2 So_4 The density = 1.34 g / mL. What is the molality of a solution in which 3.0 moles of NaCl is dissol...
Explanation:The relation between Molarity, M and mass percent (%) is given by: M = (% x 10 x d) / MW Where: MW = molecular weight of solute d = density of solution Therefore: d = M x MW / (% x 10) = 3.60 x 98 / 29 x 10 =1.216 g.mL-1 ...
Why do we use "molality" instead of "molarity" when dealing with freezing depression points? A 0.186-M solution of X (Mm= 181 g/mol) has a density of 1.027 g/ml. What is the molality of X in the solution? Why molality is preferred over molarity in handling solutions? Why is a mol...
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 milliliter of solution, must be known. ...
What is the definition of solution in chemistry? A solution was made by dissolving 12.5 g of Na3PO4 in 125.00 mL of water. The volume of the resulting solution was 128 mL. Calculate the molarity and molality of the solution. Assume water has a density of 1.00 g/mL. ...
Divide it by the solute's density in g/cm³. Multiply everything by 1000 mg/g. The resulting ppm unit by volume is typically μL/L. What is the concentration in ppm when 0.5 moles of CH₄ are dissolved in 1500 ml of water? The concentration is 5,333 ppm. To get the result:...
The second advantage is that the sum of the molar concentrations is the total molar concentration. This permits calculations of density and ionic strength. The big disadvantage of molarity is that it changes according to temperature. This is because the volume of a liquid is affected by temperatur...
