Sorry my goal was to make a 100kg of 20% mixture of magnesium and citric acid. After weighing everything and mixing my total yield was 100.46 kg. I took a sample and tested it using a titration method after calculating this it said I had 110.21% Mg in my mixture so my final product is a little more than 20% magnesium. Would I just take 20/110.21 to determine that the % content is actually 20.18%.
