Symbol for mole fraction
WebJan 20, 2024 · Finding mole fraction from molality. Calculate the mole fraction of ammonia in a 2.00 m solution of N H X 3 in water. X = no.-of-moles-of-solute (no.-of-moles-of-solute) + (no.-of-moles-of-solvent) The solute is ammonia which is N H X 3 with a molar mass (MM) of 17 g m o l − 1, whereas the solvent is water or H X 2 O which has a molar mass of ... WebFor example, what is the molar concentration of a solution of 22.4 g of HCl dissolved in 1.56 L? Step 1: First, convert the mass of solute to moles using the molar mass of HCl (36.5 g/mol): 22.4gHCl × 1molHCl 36.5gHCl = 0.614mol HCl. Step 2: Now we can use the definition of molarity to determine a concentration:
