Final answer:
The mass of 0.47 moles of C2H8O4 is 35.6 grams.
Step-by-step explanation:
To find the mass of 0.47 moles of C2H8O4, we can use the conversion factor that relates moles to grams. The molar mass of C2H8O4 is calculated by adding up the atomic masses of each element: (2 * 12.01 g/mol + 8 * 1.01 g/mol + 4 * 16.00 g/mol) = 76.08 g/mol. So the mass of 0.47 moles of C2H8O4 is calculated by multiplying the number of moles by the molar mass: 0.47 mol * 76.08 g/mol = 35.6 g.
