Answer: 241.6 grams of CO2
Explanation: you take 84.3 grams C5H12 and divide it by 72.15 grams of C5H12(which is the molar mass) you take that answer and calculate the mols of CO2 by multiplying the 1.168 you got before and multiply it by 5. You take the answer you get from that and multiply it by the molar mass of CO2 and get the theoretical yield and then you just plug it in. 94= (x/257.02)x100 and solve to find x which is the actual yield.
Oh this is extremely hard...i might just die lol jk its the last one measuring cylinder :)
The concentration of the solution in mass percent is 60%.
<h3>What is the mass percent?</h3>
The concentration of a substance can be expressed in mass percent. This refers to the percentage of the solute that is contained in the solution.
Thus we can write;
Mass percent = Mass of solute/ Mass of solution * 100/1
Mass percent = 1.5kg/1.5kg + 1 Kg * 100/1
Mass percent = 60%
Hence, the concentration of the solution in mass percent is 60%.

It is true that methane, which is a greenhouse gas and contributes to global warming.
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range.
Global warming is rise in the average temperature of the Earth's climate system.
Most often greenhouse gases are carbon dioxide (CO2) and methane (molecular formula CH4). These gases come from burning multiple substances: coal, petroleum, plastic and natural gas.
Balanced chemical reaction of combustion of methane:
CH₄ + 2O₂ → CO₂ + 2H₂O
Greenhouse gases are so difficult to measure, because carbone dioxide, methane, chlorofluorocarbons comes from multiple sources, some of which are relatively hard to measure.
