The volume formula is mass ÷ density:

V= 550 g ÷ 4.920 g/mL
V= 111.78...≈ 111.8 8 mL

Therefore, the answer is A, 111.8 mL

Answer:

111.8 mL is the volume of this piece of metal.

Explanation:

Mass of the unknown sample = m = 550.0 g

Volume of the unknown sample = V = ?

Density of the sample,d = 4.920 g/mL

[tex]Density=\frac{Mass}{Volume}[/tex]

[tex]d=\frac{m}{V}=4.920 g/mL=\frac{550.0 g}{V}[/tex]

[tex]V=\frac{550.0 g}{4.920 g/mL}=111.78 mL\approx 111.8 mL[/tex]

111.8 mL is the volume of this piece of metal.
