Hi,

Can you kindly help me how to simply calculate K2O-CaO-SiO2 and K2O-Fe2O3-SiO2-CaO for 250 mL.

Ethanol: 175 mL (70%).
Chemical agents: 75 mL (30%).

For calculation:

Purity, %:

K2O - 99.9
CaO- 98.2
SiO2-99.99
Fe2O3 - 99

Molar weight, g/mol:

K2O - 94.20
CaO- 56.08
SiO2-60.10
Fe2O3 - 159.69


Density, g/cm3:

K2O - 2.35
CaO- 3.35
SiO2-2.32
Fe2O3 - 5.24


Thanks
