Acetylsalicylic acid, or aspirin, has the formula, C9H8O4. A typical extra-strength tablet of the analgesic contains 500.0 mg of acetylsalicylic acid.
1) Determine the molar mass (also called molecular weight) of acetylsalicylic acid and report it to 5 significant figures with correct units? value unit?
2) Determine the number of moles of acetylsalicylic acid in one extra strength tablet. Just report the number of moles in decimal form (like 0.005 not 5 E-3 or 5 x 10^-3). No unit is needed?
3) Determine the number of molecules of acetylsalicylic acid in one extra strength tablet. Just report the number of molecules using scientific notation (like 8.29x10^24) (No unit is needed here either! No spaces between characters here!)
