When 4.86 g of a nonelectrolyte solute is dissolved in water to make 445 mL of solution at 29 °C, the solution exerts an osmotic pressure of 865 tor. What is the molar concentration of the solution? concentration: M How many moles of solute are in the solution? moles of solute: mol

None

A particular solute is dissolved in a solvent resulting in a solution that is 54.0 % solute by mass. If the molar mass of the solute is 178.10 g/mol, what is the molality of the solution? (Assume the solute is a nonelectrolyte).

A solution is made using 121.8 mL of acetonitrile (density 0.7766 g/mL) and 250.0 mL of water (density 1.000 g/mL). What is the molality acetonitrile in water?

A 1.13 M solution of KOH has a density of 1.05 g/mL. The molality of solution is ______ 2.98 m 2.24 m 1.14 m 1.98 m

7. A 14.5 g sample of a nonionic solute is dissolved in 50.0 g of water. The solution freezes at -2.50 °C. Calculate the molar mass of the solute.

When 17.4 ml of a solute is dissolved into 25.0 ml of water, the volume of a solution becomes 28.2 ml. What is the v/v concentration of the solution? 1.38.3% 2.61.7% 3.88.7% 4.30.4% 5.69.6%

Part A The solution concentration unit of molarity (M) is related to the moles of solute and volume of solution as follows: Moles solute Molarity (M) Liters solution Solutions are sometimes prepared from a solute that is already dissolved, and one reason for the need to do so is if the solute is not stable in air. When preparing a solution of a specific concentration from a more concentrated solution, first add the volume of solution that contains the number of moles needed, and then fill to the requisite volume with solvent. Hypochlorites, which are strong oxidizers, are examples of such compounds. Sodium hypochlorite, NaOCI, is the active ingredient in many "bleach" products. Suppose you were preparing 1.0 L of a bleaching solution in a volumetric flask, and it calls for 0.24 mol of NaOCl. If all you had available was a jug of bleach that contained 0.73 M NAOCI, what volume of bleach would you need to add to the volumetric flask before you added enough water to reach the 1.0 L line?…
