When you are dealing with gases, it is necessary to have values for pressure and temperature. SInce no values are provided, I'll assume you are at STP - 1 atm and 273.15 K.
What basically takes place is the combustion of sucrose, or table sugar.
The first thing you must look for is mole ratios, that will give you an idea on how to proceed once you determine how many moles of sucrose you have.
Notice that every 1 mole of sucrose needs 12 moles of oxygen for the reaction to take place - you have a
Determine the moles of sucrose you have by using its molar mass -
We've established that you need 12 times more moles of oxygen, so
Now that you know how mnay moles of oxygen you have, you can use the fact that 1 mole of any ideal gas occupies exactly
If 1 mole occupies
If you're not at STP, use the ideal gas law equation to solve for
2.09 litres of
The
I will assume we are at NTP where the volume of 1 mole of gas = 24 litres.
From the equation we can see that:
1 mole of gummy bear needs 12 moles
1 mole needs
So 342g needs 288 litres
So 1g needs
So 2.68g needs
