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?

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

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

$Density=\frac{Mass}{Volume}$

$d=\frac{m}{V}=4.920 g/mL=\frac{550.0 g}{V}$

$V=\frac{550.0 g}{4.920 g/mL}=111.78 mL\approx 111.8 mL$

111.8 mL is the volume of this piece of metal.
