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?
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
So for the example above would the moles be 0.18 mol?
molality x kg solvent is not your answer.
