Question

A sample of an unknown metal (density = 4.920 g/mL) weighs 550.0 g. What is the volume of this piece of metal?

a.
111.8 mL

b.
none of these

c.
2.706 × 10^3 mL

d.
1.118 × 10^5 mL

e.
8.945 × 10^–3 mL

Answer 1

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 2

111.8 mL is the volume of this piece of metal.

Step-by-step 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

`Density=(Mass)/(Volume)`

`d=(m)/(V)=4.920 g/mL=(550.0 g)/(V)`

`V=(550.0 g)/(4.920 g/mL)=111.78 mL\approx 111.8 mL`

111.8 mL is the volume of this piece of metal.
