To find the number of moles in 325 g of CO2, you need to use the formula:

Number of moles = mass of substance (g) / molar mass of substance (g/mol)

First, you need to calculate the molar mass of CO2. The molar mass of carbon (C) is approximately 12.01 g/mol and the molar mass of oxygen (O) is approximately 16.00 g/mol. Since CO2 has one carbon atom and two oxygen atoms, its molar mass is:

12.01 g/mol (for C) + 2 * 16.00 g/mol (for O) = 44.01 g/mol

Then, you can calculate the number of moles:

Number of moles = 325 g / 44.01 g/mol = 7.38 moles

So, the answer is 7.38 moles.
