Answer:

111600 moles

Explanation:

Number of moles= Mass ×Mr, where Mr is the relative molecular mass of the substance of interest. Note that the mass is calculated in terms of grams (1 kg= 1000 g), while the Mr can be found using the periodic table.

Mass of iron

= 2 kg

= 2(1000)

= 2000 g

Mr of iron= 55.8

Number of moles

= 2000(55.8)

= 111600 mol
