Answer 1

The density of the metal is 21.675 g/mL.

The volume of metal with mass of 64.9 grams is 2.994 mL.

Step-by-step explanation:

Density is defined as mass present in unit volume of the substance.

`Density=(Mass)/(Volume)`

Mass of unknown metal = m = 427.0 g

Volume of the unknown metal = v = 19.7 mL

Density of the unknown metal = d

`d=(m)/(v)=(427.0 g)/(19.7 mL)=21.675 g/mL`

Mass of the same unknown metal = M = 64.9 g

Volume of same unknown metal with mass M = V

Density of the metal = d = 21.675 g/mL

`21.675 g/ mL=(64.9 g)/(V)`

V = 2.994 mL
