The question asks to find the mass of iron needed to produce a certain amount of NaBr. How would I begin solving this question given the formulas after balancing them?

[Daniel P 3J]

To find the mass of iron needed to produce a certain amount of NaBr, follow these steps:

Balance the chemical equation involving iron and the reactants producing NaBr.
Use stoichiometry to relate the moles of NaBr to the moles of iron.
Convert moles of iron to mass, using the molar mass of iron from the periodic table.

This process involves using the balanced equation to establish mole ratios, then applying these ratios to find the mass of iron.
