急问~~如何做这到化学题?
Phosphorus can be prepared from calcium phosphate by the following reaction.
2 Ca3(PO4)2(s) + 6 SiO2(s) + 10 C(s) → 6 CaSiO3(s) + P4(s) + 10 CO(g)
Phosphorite is a mineral that contains Ca3(PO4)2 plus other non-phosphorus-containing compounds. What is the maximum amount of P4 that can be produced from 3.7 kg of phosphorite if the phosphorite sample is 70.% Ca3(PO4)2 by mass? Assume an excess of the other reactants

以我的理解
3.7 kg Ca3(PO4)2中有70.% 是纯净的Ca3(PO4)2
要用这些Ca3(PO4)2制取P4,求能制得多少?
2Ca3(PO4)2 + 6SiO2+10C→6CaSiO3+P4+10CO
620 124
3700x70.% X
X=518g
不知对不对
