Question

Дано: Mg 3 (PO4)2 i (Mg) - ? WIP) -? W(0) -?​

Answer 1

Ответ:

Mr(Mg3(PO4)2) = 24*3 + 31*2 + 16*8 = 262

W(Mg) = Ar(Mg) * n / Mr(Mg3(PO4)2) *100% = 24*3 / 262 *100% =27%

W(P) = Ar(P) * n / Mr(Mg3(PO4)2) *100% = 31*2 / 262 *100% = 24%

W(O) = Ar(O) * n / Mr(Mg3(PO4)2) *100% = 16*8 / 262 *100% =49%
