Question

Use the measurements in the table to determine which unidentified metal has the highest density.

Metal Volume Mass
A 10.5 cm3 122 g
B 14.2 cm3 132 g
C 16.1 cm3 115 g
D 12.7 cm3 126 g

Answer 1

Metal A has the highest density.

Step-by-step explanation:

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

`Density=(Mass)/(Volume)`

Density of metal A

Mass of metal = 122 g

Volume of metal =
`10.5 cm^3`

`D=(122 g)/(10.5 cm^3)=11.61 g/cm^3`

Density of metal B

Mass of metal = 132 g

Volume of metal =
`14.2 cm^3`

`D=(132 g)/(14.2 cm^3)=9.29 g/cm^3`

Density of metal C

Mass of metal = 115 g

Volume of metal =
`16.1 cm^3`

`D=(115 g)/(16.1 cm^3)=7.14 g/cm^3`

Density of metal D

Mass of metal = 126 g

Volume of metal =
`12.7 cm^3`

`D=(126 g)/(12.7 cm^3)=9.92 g/cm^3`

Metal A has the highest density.

Answer 2

ANSWER: A



EXPLANATION:

THE FORMULA FOR DENSITY IS MASS DIVIDED BY VOLUME.


D= M/V


So divide the mass by the volume.

For A, 122 divided by 10.5 is 11.62

For B, 132 divided by 14.2 is 9.295

For C, 115 divided by 16.1 is 7.143

For D, 126 divided by 12.7 is 9.921


A IS THE ANSWER BECAUSE ITS THE LARGEST AMOUNG THE OTHERS.
