Answer:
The density of object is 13 g/mL.
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.
