How should the solubility of potassium hydroxide in the table be understood?

Reply #22020-12-24

Taking the first row of the table as an example, 44 moles of KOH weigh 44 x 58 = 2552 grams, while 1000 moles of water weigh 18000 grams. The solubility is 2552 / (2552 / 18000) = 12.4%. The molar ratio is 1000 / 44 * 100 = 2273. When filling out the table, some people use molecular weight values with different levels of precision, resulting in approximate figures in the table.
