Millions of Tons of Phosphoric Acid Are Manufactured by the Treatment

Millions of tons of phosphoric acid are manufactured by the treatment of Ca₅F(PO₄)₃ with 55% by mass H₂SO₄ in water (density = 1.993 g/mL). How many L of this sulphuric acid solution are required to synthesize 1.0 x 10⁶ kg of H₃PO₄ by the following unbalanced reaction?H₂SO₄ + Ca₅F(PO₄)₃ $\rarr$ H₃PO₄ + CaSO₄ + HF
