Mr(K3PO4) = 39*3 + 31 + 16*4 =212
W(K) = Ar(K) *n / Mr(K3PO4) *100% = 39*3 / 212 *100% =55%
W(P) = Ar(P) *n / Mr(K3PO4) *100% = 31*1 / 212 *100% =15%
W(O) = Ar(O) *n / Mr(K3PO4) *100% = 16*4 / 212 *100% =30%
Mr(Cu(OH)2 = 64 + 16*2 + 1*2 =98
W(Cu) = Ar(Cu) *n / Mr(Cu(OH)2) *100% = 64*1 / 98 *100% =65%
W(O) = Ar(O) *n / Mr(Cu(OH)2 *100% = 16*2 / 98 *100% =33%
W(H) = Ar(H) *n / Mr(Cu(OH)2 *100% = 1*2 / 98 *100% = 2%
