The reaction for the burning of one type of match tip is as follows:
P4S3(s) + 8 O2(g)----> P4O10(g) + 3 SO2(g)
What volume in L of SO2 at STP can be produced by the burning of 1.00 g P4S3 in excess O2?
Here is a worked example of a stoichiometry problem.
Ok but What volume in L of SO2 at STP can be produced by the burning of 1.00 g P4S3 in excess O2?
Follow the steps in the example I gave you. Your follow up just repeats the question. We help you do your homework but we don't do it for you. If you have questions about the steps I shall be happy to explain further if you will make it clear as to what you don't understand.
i don't see the example you gave me.

I still don't get how to get the answer.
To find the volume of SO2 produced at STP from the burning of 1.00 g P4S3, you need to follow a series of steps. Here's how you can calculate it:
Step 1: Determine the number of moles of P4S3.
To find the number of moles, you need to use the molecular weight of P4S3. The molecular weight can be calculated by adding the atomic masses of phosphorus (P) and sulfur (S), multiplied by their respective subscripts.
P4S3 = (4 x atomic mass of P) + (3 x atomic mass of S)
You can find the atomic masses of P and S from the periodic table.
Step 2: Calculate the number of moles of SO2 produced.
From the balanced chemical equation, you can see that the stoichiometric ratio between P4S3 and SO2 is 3:1. Therefore, for every 3 moles of P4S3, 1 mole of SO2 is produced. Use this ratio to calculate the number of moles of SO2.
Step 3: Convert moles of SO2 to volume at STP.
STP stands for standard temperature and pressure, which is defined as 0 degrees Celsius and 1 atmosphere of pressure.
At STP, 1 mole of any ideal gas occupies 22.4 liters.
Convert the moles of SO2 to liters at STP using this conversion factor.
By following these steps, you can find the volume in liters (L) of SO2 produced at STP. Remember to consult a periodic table to get the atomic masses of P and S and use the appropriate conversion factors to carry out the calculations.
