Question

Note: The mass of carbon dioxide gas produced during the reaction can be determined by how m mass was lost from the chemical reaction. Think about it for a moment; those bubbles that were forming carbon dioxide gas molecules escaping from the beaker, while all the other chemicals remained behind. You must first compute the combined mass of vinegar and baking soda you started with, and from this subtract the mass of your solution after the reaction was complete. That difference will be the amount of carbon dioxide generated during the reaction Data for Trial #2: Mass of empty flask: 24 Mass of flask plus baking soda:_ 28.42, Mass of baking soda (calculated): 1:49 Mass of graduated cylinder with 50mL of vinegar: Mass of graduated cylinder after vinegar is poured out: 69.86 8 20.33 , 49.538 77.22, Mass of vinegar transferred (calculated): Mass of the flask with solution (after reaction is complete): Mass of the solution (calculated): Combined mass of vinegar plus baking soda (calculated): () 8 (Y-X) Mass of carbon dioxide gas produced during reaction (calculated):

please help me calculate.

Answer 1

The answer to this question is quite simple it is based on the law of conservation of mass

Here we have all the data required

Now as stated we have to find out X, Y and there difference which is mass of CO₂

Now we have mass of beaker + solution = 77.22 gram

Out of which beaker mass is = 26.93

So X = 77.22 -26. 93

= 50.29 gram = X

Now Y is total vinegar, baking soda

So

Y = 1.49 + 49.53

= 51.02 gram

So X-Y = 51.03 - 50.29

=0.74 gram of CO₂ is produced
