I think the answer is 1.25 grams actually i think i’m wrong
The correct answer is 0.15.
We are aware that there is 0.05 mol of an unidentified hydrocarbon we will refer to as "X" and that its burning produces 6.6 g of carbon dioxide and 3.6 g of water.
These quantities might be converted to moles by applying the following formula:
amount= mass/ relative atomic mass
Thus, the following equation may be written for H2O: moles = 3.6 / 18 = 0.2 and for CO2: moles = 6.6 / 44 = 0.15.
0.05X + x'O2 = 0.15CO2 + 0.2H2O
This may be made simpler by dividing through by 0.05 (this step is likely to be the most helpful to you), resulting in:
1 x + x O2 = 3 co2 + 4 H2O
The hydrocarbon must have been the source of all the carbon in the carbon dioxide and all the hydrogen in the water.
Accordingly, 4 x 2 = 8 moles of H and 3 x 1 = 3 moles of C.
There are 3/1 = 3 Cs and 8/1 = 8 Hs in one X molecule.
This clearly identifies C3H8 or propane as the hydrocarbon X (dividing by 1 seems unnecessary, but it illustrates the process to use if there were more than one mol of X in the first equation).

We should Turn off the Bunsen burner, move away any other combustible materials, Smother the fire with a watch glass or damp cloth and notify the teacher immediately.
The use of Bunsen burners poses a fire risk. They generate an open flame and burn at a high temperature, which increases the risk of an accident. It is crucial that the following rules are followed for everyone working in a laboratory's safety and convenience. In the event of a fire, sound the nearest fire alarm pull station, alert all lab staff, and leave the area immediately.

What are the choices? I'll answer once you tell me those
Aristotle considered correct over Democritus based on their time period because Aristotle was more popular than Democritus and had a better reputation, and his philosophical points overcame Democritus'. Aristotle was a famous scientist and know for being the teacher of Alexander The Great.
