1.90 What is the molality of a semimolar NaCl solution it the density of the solution is 1.16 g em? Ans. 0.44 m.

What is the molality when 0.75 mol is dissolved in 2.50 l of solvent?

Example #3: What is the molality when 0.750 mol is dissolved in 2.50 L of solvent? The answer is 0.300 m.

What is the molarity when 58.4 g of NaCl is dissolved in 500ml of solution?

When we dissolve 5.85g of NaCl in 500 ml of water then the molarity of the NaC l is 0.2M.

How do you calculate the molarity of a solution with CuCl2*2h20?

If you put 100 mL of water in first and then add the CuCl2*2H20, it will result in a solution that is more than 100 mL, which will in turn have a molarity that is not quite 1M. Always add the solute before the solvent. In short, to make x mL at y M for any solution, multiply x by y and multiply that by the molar mass of the solute.

How much oxygen is dissolved in a 1000g sample of water?

A student determines that 8.2 milligrams of oxygen is dissolved in a 1000 gram sample of water at 15°C and 1.0 atmosphere. In terms of saturation, what type of solution is this sample? Water can hold 36 grams (g) of salt in every 100 milliliters (mL). The ocean contains 3.6 g of salt in every 100 mL.

(a) 5.85 g of NaCl is dissolved in 200 mL of water. What will be the molarity of this solution? (b) Calculate the molarity of the solution obtained by dissolving 20.6 g NaBr in 500 mL of water. > (a) 5.85 g of NaCl is disso… (a) 5.85 g of NaCl is dissolved in 200 mL of water.

What is the solubility limit of glucose in 100 ml of water?

Nine grams of solid remain on the bottom. We have a saturated solution. If we now heat the mixture to 50 °C, the remaining 9 g of glucose will dissolve. At the new temperature, the solubility limit in 100 mL of water is 244 g glucose.
