Explicație:
MKCl= AK + ACl= 39 + 35,5=74,5
MNaOH=ANa + AO + AH=23 +16 +1=40
MHOH=AH + AO +AH=1+16+1=18
MCaCl2= ACa + 2ACl= 40 + 2.35.5=111
MAl( NO3 )3= A Al + 3AN + 9AO=27 + 3.14 + 9.16=213
MH2S= 2AH + AS=2 +32=34
MFeCl3= AFe + 3ACl= 56 + 3.35,5=162,5
MZnSO4=AZn + AS +4AO= 65 + 32 +4.16=161
MAg2S= 2AAg + AS=108 +32=140
MBaCO3=ABA+ 3AC + 3AO=135 + 12 + 3.16=195
MPb( NO3 )2= APb+ 2AN +6AO= calculeaza!!!!!!!!
VERIFICA CALCULELE !!!!
