M(Na2CO2) = 23*2+12*1+16*2=90g/mol
M(CuSO4)=64*1+32*1+16*4=160g/mol
M(Na2CO3)=23*2+12*1+16*3=106g/mol
M(KClO3)=39*1+35,5*1+16*3=122,5g/mol
M(MnO2)=55*1+16*2=87g/mol
M(AgCl)=108*1+35,5*1=143,5g/mol
M(SO2)=32*1+16*2=64g/mol
M(Al2(SO4)3=27*2*32*1+16*4+32*1+16*4+32*1+16*4=1984g/mol
M(K3PO4)=39*3+31*1+16*4=212g/mol
