Answer: $\text{300 g}$
From the periodic table, we can see that the mass of one mole of iron is $\text{55.845 g/mol}$. This is determined by taking the atomic weight (relative atomic mass), and writing it in g/mol.
$5 \cancel{\text{mol Fe"xx(55.845"g"/cancel"mol")="279.22 g"="300 g}}$ rounded to one significant figure
