When  of  is heated with graphite, the volume of the gases collected is . Calculate the number of moles of CO produced at STP:

Canvas Classes · Accepted Answer

Strategy:
 When  reacts with solid graphite, it produces  gas, increasing the total volume. We use the change in volume to find how much  reacted and then convert the volume of  produced into moles using the STP molar volume ().

Step 1: Write the balanced chemical equation

Step 2: Use volume change to find extent of reaction
Let  be the volume of  reacted.
- Volume of  remaining 
- Volume of  produced 
- Total final volume 
Given .

Step 3: Calculate moles of CO produced
Total  volume .
