Answer 2

Answer: Thus metal D has lowest density.

Explanation:

Density is defined as the mass contained per unit volume.

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

1. Given : Mass of metal A = 122 g

Volume of metal A = $12.5cm^3$

Putting in the values we get:

$Density=\frac{122g}{12.5cm^3}=9.76g/cm^3$

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:

$Density=\frac{129g}{15.2cm^3}=8.49g/cm^3$

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:

$Density=\frac{101g}{13.1cm^3}=7.71g/cm^3$

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:

$Density=\frac{126g}{18.7cm^3}=6.74g/cm^3$

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