Question

A 13.0 kg iron weightlifting plate has a volume of 1650 cm3 . What is the density of the iron plate in g/cm3?

Answer 1

11.0 kg = (11.0 kg)(1000 g/kg) = 11000 g
(11000 g)/(1400 cm3) = 7.857 g/cm3
Simplified = 7.86 g/cm3

Answer 2

Step-by-step explanation:

It is known that density is the amount of mass divided by volume.

Mathematically, Density =
`(mass)/(volume)`

It is given that mass is 13.0 kg or 13000 g (as 1 kg = 1000 g). And, volume is 1650
`cm^(3)`.

Therefore, calculate the density as follows.

Density =
`(mass)/(volume)`

=
`(13000 g)/(1650 cm^(3))`

=
`7.87 g/cm^(3)`

Thus, we can conclude that density of the given iron plate is
`7.87 g/cm^(3)`.
