17/02/2008 · Assume that you have a solution of an unknown solute in cyclohexane. If the solution has a freezing-point depression of 9.50Celcius, what is the molality of this solution? (The molal freezing-point constant of cyclohexane is 20.2 C/m) Freezing Point: 9.50 Moles: ? - you need the amt of grams or have the known...... Step 2 : Calculate the molal concentration of the solution. molality = moles of solute / kg of solvent moles of naphthalene = (1.60 g) (1 mol / 128 g) = 0.0125 mol naphthalene

OK, first you need to find the volume of your solution. It should be given, since NaOH is a solution. and if the amount of KHP is not very much, its volume can be ignored, so you can just use the volume of NaOH for Molarity. how to get time breaker mask in xenoverse 2 Step 2 : Calculate the molal concentration of the solution. molality = moles of solute / kg of solvent moles of naphthalene = (1.60 g) (1 mol / 128 g) = 0.0125 mol naphthalene.

How To Find Molality Of A Solution

We refer to a solution with a molarity of one as being a "one molar" solution. Molality (m) Molality is defined as the number of moles of solute per kilogram of solvent.

  • If a solution of $\ce{HNO3}$ has a molarity of 16 and a density of $1.42\ \rm{g/mL}$, what is the molality of the solution? Well, a molarity of 16 means that there are 16 moles of solute for every liter of solution.
  • Suppose a salt and glucose solution are separated by a membrane that is permeable to water but not to solutes. The NaCl solution has a concentration of 1.95g per 250 mL (molecular weight=58.5).
  • The stated molality is the LABEL molality. It is truely the number of moles of solute that were dissolved in 1 kilogram of solvent. It is what you would write on a label for the bottle of solution that was mixed. Very easy to calculate too: Take the mass of the solute used, divide it by its molar mass, and then divide that by the number of kilograms of solvent used.
  • 23/05/2008 · I know this question is much more simple than I am making it out to be but I have hit a mental block. I have a lab where I know the freezing point of water is -82.0 degrees celsius and I need to find the freezing point depression, Td, and molality of 2 unknown substances.
