Answer:
447,25k
Explanation:
According to the ideal gas law
Where:
P: is the pressure of the gas in atmospheres.
V: is the volume of the gas in liters.
n: number of moles of the gas
R: ideal gas constant
T: absolute temperature of the gas in kelvin
now using:
Vertical Column is a group
Horizontal is Period
Aliki earth metals is a group
Lithium- Neon is both
Based on electrons are both
Number of electron shells is both
The formula of Density is known as:
Density = mass/volume
Units: g/cm^3
Hope this helps!
In every reaction, mass cannot be destroyed nor created as defined by the law of conservation of mass. Energy also cannot be destroyed when a chemical reaction takes place
