Question

Fe2(SiO3)3 ; W(Fe)-? ; W(Si)-? ; W(O)-?

Answer 1

M(Fe2(SiO3)3) = 340

W(Fe) = 112/340*100% = 33%

W(Si) = 84/340*100% = 25%

W(O) = 144/340*100% = 42%

Answer 2

In Fe2(SiO3)3, the chemical symbol for iron is Fe, silicon is Si, and oxygen is O.

Using these symbols, we can determine the chemical formulas for other compounds:

W(Fe) = Fe W(Si) = Si W(O) = O
