After a fire, the ashes have less mass and take up less space than the trees and vegetation before the fire. How can this be explained in terms of the Law of Conservation of Mass?

Fire expends ENERGY which is a by-product of conversion of matter.
The calories or therms of a fire equal a certain amount of mass.
When MATTER (Electron) and ANTI-MATTER (Positron) collide they don't inhillate each other with nothingness, they always realse TWO gamma particles.
The ENERGY of the TWO gamma particles CONSERVES the MASS of the ELECTRON and The POSITRON
This is what Einstein meant by E=mc2
ENERGY has physical properties than can be measured.
These properties equal the mass that no longer exists after you measure the mass BEFORE and AFTER
The AFTER MASS + the ENERGY MUST equal the BEFORE MASS to at least 99.999%
You must take heat, light and other PARTICLES into consideration.
Their MASS plus their ENERGY

this can be explained in terms of the Law of Conservation of mass because you just have to multiply the number of amount that was lost during the fire by 5 ;

The Law of Conservation of Mass states that matter cannot be created or destroyed. When wood burns, it combines with oxygen to produce ash, carbon dioxide, and water vapor. Therefore, while ashes weigh less, the mass of the reactants equals the mass of the products if all gases are accounted for.
