Question: You take an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen) with a mass of 1.00 g, burn it in air, and collect 2.20 g of carbon dioxide and 0.400 g water. The molar mass of aspirin is between 170 and 190 g/mol. The molecular form of aspirin is:
[A] C8H10O5
[B] C10H6O4
[C] C6H8O5
[D] C9H8O4
[E] none of these
