Answer:

The density of object is 13 g/mL.

Step-by-step 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:

Volume= 7 mL

Mass= 91 g

Density of object = ?

Solution:

d= m/v

d = 91 g/ 7 mL

d = 13 g/mL

The density of object is 13 g/mL.
