Answer :
Answer:
D. 18g
Explanation:
To get the answer, we will use an equation to convert the grams of C2H5OH to moles of C2H5OH, then I will convert the moles of C2H5OH to moles of CO2, and then I will convert the moles of CO2 to grams of CO2.
9.2g C2H5OH / 46.07g C2H5OH = 0.199 mol C2H5OH
0.199 mol C2H5OH (2 mol CO2 / 1 mol C2H5OH) = 0.398 mol CO2
0.398 mol CO2 (44.01g CO2 / 1 mol CO2) = 17.515g CO2
The answer closest to our answer is answer choice D. 18g
Therefore, the answer is D
In normal temperatures, carbon dioxide is a colorless, non-flammable gas, its calculated value is "18 gram".
Carbon dioxide calculation:
Equation:
[tex]\to \bold{C_2H_5OH\ (l)+3O_2\ (g) \to 2CO_2\ (g)+3H_2O\ (g)}[/tex]
In the above-given scenario, We'll utilize an equation that converts grams of ethanol to moles of ethanol, then converts moles of ethanol to moles of carbon dioxide, and finally, transforms the moles of carbon dioxide into grams of carbon dioxide to get the result.
Following are the calculation of the conversion of carbon dioxide:
[tex]\to \frac{9.2\ g\ C_2H_5OH }{46.07\ g\ C_2H_5OH} = 0.199\ mol C_2H_5OH\\\\\to 0.199\ mol\ C_2H_5OH \ (\frac{2\ mol\ CO_2}{ 1\ mol\ C_2H_5OH}) = 0.398\ mol\ CO_2\\\\\to 0.398\ mol \ CO_2 \ (\frac{44.01\ g\ CO_2}{1 \ mol\ CO_2}) = 17.515\ g\ CO_2 \approx 18\ g \ CO_2\\\\[/tex]
Therefore, the answer is "Option D".
