3. (12 pts) Quantifying compositions is important to understanding materials. While we were talking about elements and the periodic table in class, we mentioned molecular weight (mass) and moles. This problem is to encourage you to refresh your memory about moles and molecular mass. Vitamin C, or ascorbic acid, has a chemical formula of C&H:06. (A) You have some quantity of Vitamin C, which happens to contain one mole of oxygen. How many moles of hydrogen does this contain? How many moles of Vitamin C do you have? (B) A typical multivitamin contains 1000 mg of Vitamin C. If each vitamin tablet is 2.5g, what mass of tablets would be needed to contain a mole of vitamin C? Now, extend your understanding of moles beyond elements: (C)If you have a mole of football, how many footballs do you have? (D) What is the mass of a mole of football? How does this compare to the mass of the earth? (i.e., state the mass in terms of the fraction of earth's mass.)
