Va rog !! Cat mai repede posibil !!

Answer 1

M(SO2)=64g/mol
M(P2O5)=111g/mol
M(N2O5)=108g/mol
M(CO2)=44g/mol

M(LiOH)=24g/mol
M(NaOH)=40g/mol
M(KOH)=56g/mol
M(Ca(OH)2)=74g/mol

M(H2SO4)=98g/mol
M(H3PO4)=98g/mol
M(HNO3)=63g/mol
M(H2SiO3)=78g/mol

M(Na3PO4)=164g/mol
M(Mg3(PO4)2)=262g/mol
M(AlPO4)=122g/mol
M(K3PO4)=212g/mol

M(Na2SO4)=142g/mol
M(CuSO4)=160g/mol
M(MgSO4)=120g/mol
M(CaSO4)=136g/mol
