Answer 1

Resposta:Segue as contas abaixo na explicação

Explicação:

1) AI2O3-->27x2+16x3-->54+48-->102 g/mol

2) HCI -->1x1+35,5x1-->1+35,5-->36,5 g/mol

3) AICI3-->27x1+35,5x3-->27+106,5-->1335,5 g/mol

4) NaOH-->23x1+16x1+1x1-->23+16+1-->40 g/mol

5) Ba(NO3)2-->137x1+14x2+16x6-->137+28+96-->261 g/mol

6) Na2SO4-->23x2+32x1+16x4-->46+32+64-->142 g/mol

7) NaOH -->23x1+16x1+1x1-->23+16+1-->40 g/mol

8) HNO 3-->1x1+14x1+16x3-->1+14+48-->63 g/mol

9) Ba(OH)2-->137x1+16x2+1x2-->137+32+2-->171 g/mol

10) MgCl2-->24x1+35,5x2-->24+71-->95 g/mol
