For example if you burnt 100 Kg of solid object, would the gases produced weigh 100 Kg?

No because it undergoes a chemical change when burn't.
If you were to heat a compound from solid --> liquid ---> gas it would still have the same mass

Though also bear in mind that burning often means you add oxygen, so that whatever the compound is actually changes.
e.g. When you burn carbon, the gas you produce (CO2) has more mass because of the extra oxygen. However, the mass of carbon is the same.
