How to convert weight percent to mole fraction - physicscatalyst
Web6 sep. 2024 · First find the total mass of the solution: total mass = 6 g sodium hydroxide + 50 g water. total mass = 56 g. Now, you can find the mass percentage of the sodium hydroxide using the formula: mass percent = (grams of solute / grams of solution) x 100. mass percent = (6 g NaOH / 56 g solution) x 100. mass percent = (0.1074) x 100.
