Answer:
Density if iron shot = 7.92 g/ml (2 sig. figs.)
Explanation:
By definition, density is mass per unit volume. That is,
Density (D) = mass(m)/Volume(V)
mass(m) = 28.5g (given)
Volume(V, of iron shot) = 49.10ml - 45.5ml = 3.6ml
Substitutuing into D = m/V = 28.5g/3.6ml = 7.9166667 g/ml (calc.ans)
≅ 7.92 g/ml (2 sig. figs.)
Hope this helps. :-)
