JEE Main 2025 — Some Basic Concepts Of Chemistry Question with Solution

Consider the following reaction occurring in the blast furnace:

$${\mathrm{Fe}}_3{\mathrm{O}}_{4(\mathrm{s})}+4{\mathrm{CO}}_{(\mathrm{g})}\to 3{\mathrm{Fe}}_{(\mathrm{l})}+4{\mathrm{CO}}_{2(\mathrm{g})}$$

' $x$ ' kg of iron is produced when $2.32\times 10^3\mathrm{kg}{\mathrm{Fe}}_3{\mathrm{O}}_4$ and $2.8\times 10^2\mathrm{kg}\mathrm{CO}$ are brought together in the furnace. The value of ' $x$ ' is _________ . (nearest integer)

{Given: molar mass of ${\mathrm{Fe}}_3{\mathrm{O}}_4=232\mathrm{g}{\mathrm{mol}}^{-1}$

molar mass of $\mathrm{CO}=28\mathrm{g}{\mathrm{mol}}^{-1}$

molar mass of $\mathrm{Fe}=56\mathrm{g}{\mathrm{mol}}^{-1}$}
