A chemical formula can be used to determine the makeup of a substance. It tells you what elements make up a particular substance, like H2O is the chemical formula of water.
Ultraviolet light has higher frequency and higher radiant energy.

Answer:
electrons/electron density
Explanation:
Answer:
The density of object is 5 g/ cm³.
Explanation:
Density:
Density of an object is equal to its mass 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 = 15 g
volume = 3 cm³
density = ?
Solution:
d = m / v
d = 15 g/3 cm³
d = 5 g/ cm³
so the density of object is 5 g/ cm³.
