When calculating consumption of certain RO chemicals for reverse osmosis pretreatment or post-treatment, it is often necessary to convert into moles. (a) the molar mass of M is g/mol (b) the value of x is. 5. If the solubility ... (NH3)2* are 2500 and Ko, respectively. Given that the solubility of AgCl ... then X (NH3) = 1.8/6.32 = 0.285. Given: Mass of solute = 30.6 g. Mass of solvent = 81.3 g molar mass(NH3) = 14 + 3x1 = 17 g/mol molar mass(H2O) = 2x1+16 = 18. during melting, with almost no reduction of the molar mass at this stage, revealing NH3 digestion as a promising method for PHA recovery.
