Answer 1

Mr(NaCl) = Ar(Na) * N(Na) + Ar(Cl) * N(Cl) = 23 * 1 + 35,5 * 1 = 58,5;

Mr(CaCO3) = Ar(Ca) * N(Ca) + Ar(C) * N(C) + Ar(O) * N(O) = 40 * 1 + 12 * 1 + 16 * 3 = 100;

Mr(HNO3) = Ar(H) * N(H) + Ar(N) * N(N) + Ar(O) * N(O) = 1 * 1 + 14 * 1 + 16 * 3 = 63;

Mr(C6H12O6) = Ar(C) * N(C) + Ar(H) * N(H) + Ar(O) * N(O) = 12 * 6 + 1 * 12 + 16 * 6 = 180;

Mr(AgNO3) = Ar(Ag) * N(Ag) + Ar(N) * N(N) + Ar(O) * N(O) = 108 * 1 + 14 * 1 + 16 * 3 = 170;

Mr(KI) = Ar(K) * N(K) + Ar(I) * N(I) = 39 * 1 + 127 * 1 = 166.
