The volume of gas is 3.571 L.
Step 1. Write the balanced equation.
Step 2. Calculate the moles of
Step 3. Use the Ideal Gas Law to calculate the volume of CO₂
STP is 100 kPa and 273.15 K.
The great thing about STP is that the ideal gas law calculations have already been done for you for 1 mole of a gas.
At STP conditions, 100.0 kPa and 0 degrees C, to be more precise, 1 mole of any ideal gas occupies exactly 22.71 L. This is known as the molar volume of a gas at STP.
So, in your case, once you get the number of moles of carbon dioxide produced, you can multiply that value by the molar volume of a gas at STP to get the volume you need
So, don't forget about the molar volume of a gas at STP. If nothing else, you can use it to double check the calculations you've made using the ideal gas law.
At STP, for n moles of ideal gas
