1. CaO
Ca = 40u
O = 16u
mCaO = 40u + 16u
mCaO = 56u
2. K2O
K = 39u
O = 16u
mK2O = 39u x 2 + 16u
mK2O = 94u
3. Al2O3
Al = 27u
O = 16u
mAl2CO3 = 27u x 2 + 16u x 3
mAl2CO3 = 102u
4. NH3
N = 14u
H = 1u
mNH3 = 14u + 3 x 1u
mNH3 = 17u
5. HCl
H = 1u
Cl = 35,5u
mHCl = 1u + 35,5u
mHCl = 36,5u
6. PbO2
Pb = 207u
O = 16u
mPbO2 = 207u + 16u x 2 =
mPbO2 = 239u
