Chromite ore + Na2CO3 + O2 → Insoluble product Calculate the molar mass of insoluble product formed.

Question

Chromite ore \(+\ Na_2CO_3+O_2 \rightarrow\) Insoluble product Calculate the molar mass of insoluble product formed.

(Given : Molar mass of Cr = 52 g/mol, Na = 23 g/mol, Fe = 56 g/mol, 0 = 16 g/mol)

Answer 1

Answer is "160"  

Molar mass of Fe₂O₃ 

\(\Rightarrow 2(56) +3(16)\) 

\(\Rightarrow 160\)
