The law of conservation of mass clearly states that the mass could not have been destroyed (nor created for that matter). Theresore, when the reaction with air took place, part of the mass of the sucrose would be converted to a gaseous state, and probably a chemical reaciton with the air would create a different compound, and would escape into the atmosphere. hope this answers the question.
Thermal loss in dielectric heating
No, because heating matter dose not effect its mass.
No.
An increase in mass is normally caused by chemical reactions with other materials, Similarly, a loss in mass can be explained by a physical change of state or by the removal of elements or compounds by chemical reactions.
By the heating the colligion between atoms will increase so the mass of the air also increases.We cant measure the mass of air but we can measure it with the help of a container.
Weigh mass before heating and weigh mass after heating. Before mass - after mass.
At high temperature sucrose is thermally decomposed.
What mass of sucrose C12H22O11 is needed to make 500 ...
Yes, the mass of the iron filings will most likely change after being heated and reweighed. Heating the iron filings can cause the formation of oxides through oxidation reactions, which can lead to the loss of some mass. Additionally, heating can also cause some of the iron filings to vaporize, resulting in further mass loss.
This can be confirmed by doing a chemical analysis.
Because of the loss of the water of hydration.

Thermal loss in dielectric heating
The percent, by weight of 17g of sucrose in 188g of water is calculated as follows Mass of Sucrose / Total Mass of Solution *100% = 17 / (188 + 17) * 100 = 8.29%
342.3 g/mol
To get a 12 mass% sucrose sol'n dissolve 12.0 g sucrose in 88.0 gram (near 88 ml) of water.
I assume you mean the molecular mass. Its molecular mass is 342.3g/mol
