The molar mass of the water insoluble product formed from the fusion of chromite ore ( ( FeCr ₂ O ₄ ) ) with ( Na ₂ CO ₃ ) in presence of ( O ₂ ) is _______ ( g mol ⁻¹ ).

Correct answer

0

Step-by-step solution

FeCr ₂ O ₄+ Na ₂ CO ₃+ O ₂ Na ₂ CrO ₄+ Fe ₂ O ₃+ CO ₂ Insoluble product will be Fe ₂ O ₃ molar mass =56 2+16 3 aligned & =112+48 & =160 aligned
