Question

Quizplus · Accepted Answer

The mole fraction of phosphoric acid can be calculated using the formula:Mole fraction of H3PO4 = (Mass of H3PO4 / Molar mass of H3PO4) / (Mass of solution / Molar mass of water)Given that the mass of the solution is 100 g and the mass of H3PO4 is 38.5 g, we can calculate the mole fraction of H3PO4 as:Mole fraction of H3PO4 = (38.5 g / 98 g/mol) / (100 g / 18 g/mol) = 0.103
