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 *12 times more moles* of oxygen.

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 **STP** - this is known as the molar volume of a gas.

If 1 mole occupies

**STP**.

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
