Once the empirical formula is found, the molecular formula for a compound can be determined if the molar mass of the compound is known. Simply calculate the mass of the empirical formula and divide the molar mass of the compound by the mass of the empirical formula to find the ratio between the molecular formula and the empirical formula. The formula for solutions is: C V = n, where C is concentration in molar, V is the volume in liters, and n is the number of mols of solute. Further, n = m/Fw , where m is the mass and Fw is the formula weight of the solute.

Molarity Formula Definition: Molarity of a given solution is defined as the total number of moles of solute per litre of solution.
Mar 06, 2018 · Calculate the molality of a 60-% (w/w) solution of ethanol in water. Solution:From the above problems, we know that one liter of this solution contains 11.6 mol of ethanol in (893.7 – 536.2) = 357.5 g of water. The molarity of ethanol in the solution is therefore (11.6 mol) / (0.3575 kg) = 32.4 mol kg–1. George pours 500.00 mL of a 3.0000 molar solution of sodium hydroxide into a 2.000 liter volumetric flask and fills the flask up with water. What is the new molarity of the solution? 0.50000 L soln x 3.0000 mol NaOH = 1.5000 mol NaOH
