WebApr 4, 2024 · Around 60 grams. Explanation: We have a 3.5 M solution of phosphoric acid with 175 mL of it in there. This means that there are: 3.5 mol L ⋅ 0.175L = 0.6125 mol So, there exist 0.6125 moles of phosphoric acid here. Phosphoric acid has a molar mass of 97.994 g/mol. So here, the mass is: 0.6125mol ⋅ 97.994 g mol ≈ 60 g Answer link WebJul 30, 2024 · The mole fraction of phosphoric acid (H₃PO₄) in a 25.4% (by mass) aqueous solution is 0.059. Let the mass of the solution be 100 g.. Thus, the mass of 25.4% of H₃PO₄ = 25.4 g. Next, we shall determine the number of mole in 25.4 g of H₃PO₄ ; Mass of H₃PO₄ = 25.4 g. Molar mass of H₃PO₄ = (3×1) + 31 + (16×4) = 98 g/mol . Mole of H₃PO₄ =? Mole = … how to run jdk in windows 10
