Question

How many grams of carbon dioxide (CO2) are produced when 124 grams of sugar are used in a recipe?
60.6 g CO2
30.3 g CO2
121.2 g CO2

Answer 1

They gave me this C6H12O6

Answer 2

C6 H12 O6

Answer 3

Ight thanks

Answer 4

@kekeman is this a test question?

Answer 5

Nope this is for my study guide

Answer 6

These are the options:
60.6 g CO2
30.3 g CO2
121.2 g CO2

Answer 7

And here is the balanced equation:
C6 H12 O6 2C2H5OH + 2CO2

Answer 8

Divide 124g of sugar by the molar mass of sugar (C6H12O6) to get moles sugar. The balanced equation tells you that 1 mol sugar = 2 moles CO2, so multiply moles sugar * 2 to get moles CO2. Finally, multiply by the molar mass of CO2 to get mass of CO2.

Answer 9

So how do you set that up

Answer 10

So 124g divided by 342.3 g/mol

Answer 11

(124g sugar) * (moles sugar)/(molar mass sugar) * (2 moles CO2/ 1 mol sugar) * (g CO2 / moles CO2)

Answer 12

Where do you get 342.3 g/mol? The molar mass of C6H12O6 is 180.16 g/mol

Answer 13

Okay so i got 0.688277087

Answer 14

Ok, that’s your moles sugar, keep going with the rest of the stoichiometry

Answer 15

1.376554174 moles CO2

Answer 16

Good, one last step, multiply by molar mass of CO2

Answer 17

1.376554174 * 44.01 = 60.5821492

Answer 18

Good, that rounds to the answer choice 60.6g

Answer 19

Or 60.6

Answer 20

Thank you i understand now
