Question

Iron has a density of

7.86 g/c
m
3
(
1 c
m
3
=1 mL
). Calculate the volume (in
dL
) of a piece of iron having a mass of 4.58
kg
. Note that the density is provided in different units of volume and mass than the desired units of volume (
dL
) and the given units of mass (
kg
). You will need to express the density in
kg/dL
(
1 c
m
3
 = 1 mL
) before calculating the volume for the piece of iron.

Answer 1

1. 0.0786dl is the answer

Answer 2

Answer: 5.83 dL

Explanation: First convert the density to Kg/dL

Given Mass = 4.58 Kg

Given Density = 7.86 g/cm3 =7.86 g/mL

Density = 7.86 (g/mL) *100/1000(mL/g) Kg/dL

Density = 0.786 Kg/dL

From Density = Mass/Volume

Volume = Mass/Density

= 4.58/0.786 dL

=5.83 dL
