Question #61723

Answer 1

Multiply the number of moles of Fe by the molar mass of Fe.

Answer: `"300 g"`

Explanation:

From the periodic table, we can see that the mass of one mole of iron is `"55.845 g/mol"`. This is determined by taking the atomic weight (relative atomic mass), and writing it in g/mol.

`5cancel"mol Fe"xx(55.845"g"/cancel"mol")="279.22 g"="300 g"` rounded to one significant figure
