Converting to atoms

  1. Sep 17, 2008 #1
    1. The problem statement, all variables and given/known data
    You are given a 250mg tablet of Vitamin C, C6H8O6. How many atoms are in the Vitamin C sample?

    3. The attempt at a solution
    Formula Mass = 6(12.01)+8(1.01)+6(16.00) = 176.1 g/mol

    250mg (1g/1000mg)(1mole/176.1g)(6.02e23molecules/1mole) = 8.546 molecules

    How do I convert to atoms? I thought it was the same number but the webassign program said that it was incorrect.

    First of all - it is not 8.5 molecule, you have missed the exponential part.

    Second - take a look at the formula. C6H8O6 - how many carbon atoms in molecule? Hydrogen? Oxygen? Total?
