Question

The specific gravity of iron is 7.87, and the density of water at 4.00 ∘C is 1.00 g/cm3. You can use this information to find the density of iron. Find the volume occupied by 8.00g of iron.

Answer 1

\[\ \gamma = \frac{ m }{ V }\]

\[G = \frac{ \gamma _{m} }{ \gamma _{w} }\]

Answer 2

since specific gravity is the density of the material over the density of water
then you'll have the density of iron as 1.00(7.87) = 7.87g/cm3
the volume is given by the formula:
\[\rho = \frac{ m }{ V }\]
so volume would be
\[V = \frac{ m }{ \rho }\]

Answer 3

\[V = \frac{ 8g }{ 7.87g/cm3 }\]

Answer 4

@sippara recall the formulas for density and specific gravity that's all you need and you're done

Answer 5

this one's hydraulics and geotechnical though o.o
