Question

A block of metal has a volume of 14.0in3 and weighs 5.26lb .

What is its density in grams per cubic centimeter?,

Answer 1

Mass of block, m = 5.26 lb
1 lb = 453.592 g
5.26 lb = 2385.896 g
V = 14 in3
1 in = 2.5 cm
1 in3 = 15.625 cm3
14 in3 = 218.75 cm3


Density = mass/volume
= 2358.896 / 218.75
= 10.783 g/cm3

Answer 2

Answer : The density of metal is
`10.399g/cm^3`

Explanation :

Density : It is defined as the mass of a substance contained per unit volume.

Formula used :

`Density=(Mass)/(Volume)`

Given:

Mass of metal = 5.26 lb = 2385.896 g

conversion used : (1 lb = 453.592 g)

Volume of metal =
`14.0inch^3=229.419cm^3`

conversion used :
`(1inch^3=16.3871cm^3)`

By using formula, we get:

`Density=(2385.896g)/(229.419cm^3)`

`Density=10.399g/cm^3`

Thus, the density of metal is
`10.399g/cm^3`
