Second, you should be able to calculate the amount of solute in (or needed to make) a certain volume of solution. ... To get molarity we still need to divide moles of solute by volume of solution. But this time we're not given the moles of solute. We have to calculate it from the mass of NaCl.

To find "m," the molality of a solution you need to know the number of moles of solute and the number of kilograms of solvent (m = moles/kg). ... Calculate the molality of phenol? What is the equation for molality? How do you solve involving molality? Calculate the molality of the solute? How do you calculate H of a Solution?

A web site for students studying advanced chemistry courses in the UK ... 2. From your titration results you can calculate the amount (moles) of manganate(VII) used - you will need to know how to work out the amount (moles) of a substance in a solution given its concentration and volume, to get started.

The term concentration is used to indicate the amount of solute dissolved in a given quantity of solvent or solution. ... If we know the molarity of a solution we can calculate the number of moles of solute in a given volume. Thus, molarity is a conversion factor between volume of solution and moles of solute:
