Answer : The amount of carbon dioxide produced is, 197.12 grams.
Explanation : Given,
Moles of ethanol = 2.24 mole
Molar mass of carbon dioxide = 44 g/mole
The balanced chemical reaction will be,
First we have to calculate the moles carbon dioxide.
From the balanced chemical reaction, we conclude that
As, 1 mole of ethanol react to give 2 moles of carbon dioxide
So, 2.24 mole of ethanol react to give moles of carbon dioxide
Now we have to calculate the mass of carbon dioxide.
Therefore, the amount of carbon dioxide produced is 197.12 grams.
The volume of object is 3.2 ml
<h3>Explanation:</h3>Given:
Mass of the object = M = 9.6 g
Initial volume of liquid:
Final volume of liquid after displacement:
Total volume of the displaced object inside a graduating cylinder will be given as difference between the final volume and initial volume of the expanding object.
V = 3.2 ml
