Final answer:
To find the mass of 8 moles of sulfur dioxide (SO2), multiply the moles by its molar mass (64.07 g/mol), resulting in a mass of 512.56 g.
Step-by-step explanation:
To calculate the mass of sulfur dioxide (SO2), we first need to know the molar mass of SO2. The molar mass of SO2 can be calculated by adding the molar mass of sulfur (S), which is approximately 32.07 g/mol, and the molar mass of oxygen (O), which is approximately 16.00 g/mol. As there are two oxygen atoms in sulfur dioxide, the calculation would be:
Molar mass of SO2 = (1 × 32.07 g/mol) + (2 × 16.00 g/mol) = 32.07 g/mol + 32.00 g/mol = 64.07 g/mol.
Now that we know the molar mass, we can calculate the mass of 8 moles of SO2 by using the formula:
Mass = moles × molar mass
Mass of SO2 = 8 moles × 64.07 g/mol = 512.56 g.
Therefore, 8 moles of sulfur dioxide have a mass of 512.56 g.
