H²CO³-
Al²(SO⁴)³-
Ca³(PO⁴)²-
Дам 30 балов ​

Answer 1

Ответ:

N2O3: 14•2+16•3=76

H2CO3: 1•2+12+16•3=62

Al2(SO4)3: 27•2+32•3+16•4•3=342

Ca3(PO4)2: 40•3+31•2+16•4•2=310

Answer 2

Mr(N2O3) = 14×2 + 16×3 = 76

Mr(H2CO3) = 1×2 + 12 + 16×3 = 62

Mr(Al2(SO4)3) = 27×2 + 32×3 + 12×16 = 342

Mr(Ca3(PO4)2) = 40×3 + 31×2 + 16×8 = 310
