B 15.2 cm3 129 g
C 13.1 cm 101 g
D 18.7 cm3 126 g
Metal A
Metal B
Metal C
Metal D

Answer 1

The metal with the lowest density is letter D = 6.74 g/cm³

Answer 2

Answer: Thus metal D has lowest density.

Step-by-step explanation:

Density is defined as the mass contained per unit volume.

`Density=(mass)/(Volume)`

1. Given : Mass of metal A = 122 g

Volume of metal A =
`12.5cm^3`

Putting in the values we get:

`Density=(122g)/(12.5cm^3)=9.76g/cm^3`

Thus density of metal A is
`9.76g/cm^3`

2. Given : Mass of metal B = 129 g

Volume of metal B =
`15.2cm^3`

Putting in the values we get:

`Density=(129g)/(15.2cm^3)=8.49g/cm^3`

Thus density of metal B is
`8.49g/cm^3`

3. Given : Mass of metal C = 101 g

Volume of metal C =
`13.1cm^3`

Putting in the values we get:

`Density=(101g)/(13.1cm^3)=7.71g/cm^3`

Thus density of metal C is
`7.71g/cm^3`

4. Given : Mass of metal D = 126 g

Volume of metal D=
`18.7cm^3`

Putting in the values we get:

`Density=(126g)/(18.7cm^3)=6.74g/cm^3`

Thus density of metal D is
`6.74g/cm^3`
