Molare Masse?
Hallo,
Kann jemand mir bitte helfen? ich kann es nicht löse😥 aber bitte einfach
Berechne mit wie viel Liter Kohlenstoffdioxid die Atmosphäre belastet wird, wenn ein Liter Ethanol verbrannt wird. Die Dichte von Ethanol beträgt 789,3 kg pro Kubikmeter und die Dichte von Kohlenstoffdioxid beträgt 1,977 kg pro Kubikmeter und ein Liter gleich 1000 Kubikzentimeter
bitte Hilfe ich muss es abgeben
Danke
What is the reaction equation?
How much kilo is a liter of ethanol?
How much mol of ethanol are burned?
How much mol of CO2 are produced by one mol of ethanol during the decomposition?
How much mol in the concrete combustion of 1 liter of ethanol?
How much kilo CO2 are generated?
How much liter is that?
1. C2H5OH +3 O2 -> 3H2O +2CO2
Again right – and now on, the questions should help you as a guideline.
Okay, I’ll take a look at everything.
Thank you DU are very smart ðŸ ̃‰
Yes, the question was how much liter of CO2. The result is 0.763 cubic meters, which is 763 litres.
is that now: The result is the volume ?
This is the density of CO2 you mentioned
Thank you.
I have everything up to the last step
Why by 1,977
*seufzt* and don’t pay me, thank you
What is the reaction equation?
1 C2H5OH + 3 O2 –> 3 H2O + 2 CO2
How much kilo is a liter of ethanol?
1 l = 0,001 m^3
0,001 m3 * 789.3 kg/m3 = 0,7893 kg = 789.3 g
How much mol of ethanol are burned?
Molar mass of ethanol (see and add the atomic weights of the individual elements – value of the atomic weights corresponds to the molar mass): 46.07 g/mol
g : 46.07 g/mol = 17.133 mol
How much mol of CO2 are produced in the combustion of one mol of ethanol?
In the reaction equation: 2 mol
How much mol in the concrete combustion of 1 liter of ethanol?
2*17.133 mol=34.266 mol
How much kilo CO2 are generated?
Molar mass of CO2: 44.01 g/mol
44.01 g/mol * 34.266 mol = 1,508.047 g = 1,508 kg
How much liter is that?
1,508 kg: 1,977 kg/m3 = 0,763 m3 = 763 l
How should I calculate step three?
2.1 liter of ethanol is 790 kg
can they please help me until the end or I come through each other
