Hey guys, I'm a pre-pharm here at UNC-Asheville. I'm in general chem 1 at the moment and have been doing some practice problems on my own time to help me prepare for my test here in a couple of weeks. Well, anyways, I need help on a particular problem and, since I live off campus, I have no way of getting in touch with my classmates. If anyone could help me with this, I would be very thankful! I have the answer sheet that the book came with, but I just don't know how to get there using dimensional analysis. If this is against the rules, I apologize.
A sample of glucose, C6H12O6, contains 5.77E20 atoms of carbon.
A) How many atoms of hydrogen does it contain? (I know it's just twice as much, but how do I set up the analysis?) ANS: 1.15E21 H atoms
B) How many molecules of glucose does it contain? ANS: 9.62E19 C6H12O6 molecules
C) What is the mass of this sample in grams? ANS: .0287g C6H12O6
Thanks everyone!
