mFe(Oh)3 = 56u + 3*16u + 3*1u = 56u + 48u + 3u = 107u
mKOH = 39u + 16u + 1u = 56u
mMgSO4 = 24u + 32u + 4*16u = 24u + 32u + 64u = 120u
mLi3Po4 = 3*7u + 31u + 4*16u = 21u + 31u + 64u 116u
mFe(No3)3 = 56u + 3*14u + 9*16u = 56u + 42u + 144u = 242u
mZnCl2 = 65u + 2*35,5 u = 136u
mAl2S3 =2*27u + 3*32u = 54u + 96u = 150u
m(NH4)2SO3 = 2*14u + 8*1u + 32u + 3*16u = 28u + 8u + 32u + 48u = 116u
Fe(Oh)3 = 56u + 3*16u + 3*1u = 56u + 48u + 3u = 107u
KOH = 39u + 16u + 1u = 56u
MgSO4 = 24u + 32u + 4*16u = 24u + 32u + 64u = 120u
Li3Po4 = 3*7u + 31u + 4*16u = 21u + 31u + 64u = 116u
Fe(No3)3 = 56u + 3*14u + 9*16u = 56u + 42u + 144u = 242u
ZnCl2 = 65u + 2*35,5 u = 136u
Al2S3 =2*27u + 3*32u = 54u + 96u = 150u
(NH4)2SO3 = 2*14u + 8*1u + 32u + 3*16u = 28u + 8u + 32u + 48u = 116u
