One night you and your friend decided to help in agriculture. The farmer you are helping reacted 90Kg of Calcium fluoride phosphate (Cas(PO4)3F) and 30L of sulfuric acid(H2SO4), so far he has collected5Kg of hydrofluoric acid (HF) and the farmer wants to know the % yield of the HF to estimate the timeneeded to complete the reaction. Balance the equation, calculate the molecular weight and mols ofCas(PO4)3F and H2SO4 (Density of Sulfuric acid 1.84 g/cm3), Calculate the limiting reagent, the percentyield of HF and the number of molecules of so far. If the density of HF is 1.15 g/cm3 and the temperatureof the 10 L vessel HF is contained is 25 C what is the pressure of the contained in which HF is collected?Ca(H2 PO4)2 (aq) + CaSO4 (aq) + HF (g)Cas(PO4)3F (s)+H2SO4 (aq)
