Phosphorus is obtained primarily from ores containing calcium phosphate

Answer. 2. Now, we can find the mass of the ore needed to get 5.00 kg of calcium phosphate. Since the ore contains 57.8% calcium phosphate, we can calculate the mass of the ore as follows: 5.00 kg Ca3 (PO4)2 × (1 kg ore / 0.578 kg Ca3 (PO4)2) = 8.65 kg ore So, the minimum mass of the ore that must be processed to obtain 1.00 kg …
