Calculate mole solute in solution?
I added an amount of an unknown sample to a solution. I found that the molality of the solution is 0.085m and there is 0.0156kg of solvent. Calculate the moles of solute present in solution?

Thanks!

  • Chemistry -

    molality = moles of solute/kilograms of solvent

    notice how the units cancel out to moles of solute:

    (moles of solute/kg of solvent)*(kg)= moles of solute

  • Chemistry -

    So for the example above would the moles be 0.18 mol?

  • Chemistry -

    molality x kg solvent is not your answer.
