Question

Alexa has a sample of gold that has a density of 19.32g/cm. She measured its mass to be

Answer 1

Answer:

The volume of gold is 3.3 cm³.

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m³.

Other units are given below,

g/cm³, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

Mass of gold = 63 g

Density of gold = 19.32 g/cm³

Volume of gold = ?

Solution:

d = m/v

v = m/d

v = 63 g/ 19.32 g/cm³

v = 3.3 cm³.
