Final answer:
To calculate the volume of carbon dioxide produced at STP by the dehydration of methanoic acid, divide the mass of methanoic acid by its molar mass and multiply by the molar volume of a gas at STP.
Step-by-step explanation:
To calculate the volume of carbon dioxide produced at standard temperature and pressure (STP) by the dehydration of methanoic acid, you need to first determine the number of moles of carbon dioxide produced. The molar mass of carbon dioxide is 44 g/mol. You can calculate the number of moles by dividing the mass of methanoic acid (600 grams) by its molar mass (46.03 g/mol). Next, you can convert the number of moles to volume using the molar volume of a gas at STP, which is 22.414 L/mol. Multiply the number of moles by the molar volume to find the volume of carbon dioxide produced.
