Question

Помогите определить Mp для веществ: CaO, CaCO3, Ba3(PO4)2, H2CO3

Answer 1

Mr(CaO) = Ar(Ca) + Ar(O) = 40 + 16 = 56

Mr(CaCO3) = Ar(Ca) + Ar(C) + 3Ar(O) = 40 + 12 + 3 x 16 = 100

Mr(Ba3(PO4)2) = 3Ar(Ba) + 2Ar(P) + 8Ar(O) = 3 x 137 + 2 x 31 + 8 x 16 = 601

Mr(H2CO3) = 2Ar(H) + Ar(C) + 3Ar(O) = 2 x 1 + 12 + 3 x 16 = 62
