Question

За формулой речовын обчыслить видносну молекулярну масу​

Answer 1

Ответ:

M(N2) = 14*2 = 28

M(CO) = 12+16 = 28

M(Rb2O) = 85*2+16 = 186

M(Al2O3) = 27*2+16*3 = 102

M(NH3) = 14+1*3 = 17

M(H2O2) = 1*2+16*2 = 34

M(Fe3O4) = 56*3+16*4 = 232

M(BaCO3) = 137 + 12+16*3 = 197

M(KMnO4) = 39 + 55+16*4 = 158

M(Al(OH)3) = 27 + (16+1)*3 = 78

M(Hg(ONC)2) = 201+(16+14+12)*2 = 285

M(NaHCO3) = 23+1+12+16*3 = 84

Answer 2

Ответ:

Объяснение:

Mr(CO) = 12 + 16 = 28

Mr(Rb2O) = 85*2 + 16 =186

Mr(Al2O3) = 27*2 + 16*3 = 102

Mr(NH3) = 14+1*3 = 17

Mr(H2O2) = 1*2 + 16*2 = 34

Mr(Fe3O4) = 56*3 + 16*4 = 232

Mr(BaCO3) = 137 + 12 + 16*3 = 197

Mr(KMnO4) = 39 + 55 + 16*4 = 158

Mr(Al(OH)3) = 27 + 16*3 + 1*3 = 78

Mr(Hg(ONC)2 = 201 + 16*2 + 14*2 + 12*2 = 285

Mr(NaHCO3) = 23 + 1 + 12 + 16*3 = 84
