White phosphorus (123.88 g/mol) is produced by the reaction of calcium phosphate (310.18 g/mol), silicon dioxide (60.09 g/mol), and carbon (12.01 g/mol).How many grams of CO (28.01 g/mol) are produced as a by-product when 1.500*103 g SiO2 reacts with excess (Ca3PO4)2 and C? Assume 100% yield.
2 Ca3 (PO4 )2 (s) + 6 Si O2 (s) + 10 Cs) P4 (s) + 6 CaSi O3 (s) + 10 CO(g)
