SUMMARY

The discussion focuses on calculating the number of atoms in a 250mg tablet of Vitamin C (C6H8O6). The molecular weight of Vitamin C is determined to be 176.1 g/mol. The calculation shows that 250mg corresponds to approximately 8.546 molecules. To convert molecules to atoms, one must account for the number of each type of atom in the molecular formula, specifically 6 carbon, 8 hydrogen, and 6 oxygen atoms per molecule, leading to a total of 20 atoms per molecule.

PREREQUISITES
  • Understanding of molecular weight calculations
  • Familiarity with Avogadro's number (6.02e23)
  • Basic knowledge of chemical formulas and atomic composition
  • Ability to perform unit conversions (mg to g)
NEXT STEPS
  • Learn about molecular weight determination and its significance
  • Study Avogadro's number and its applications in chemistry
  • Explore the concept of moles and their conversions in chemical calculations
  • Investigate the atomic composition of other common compounds
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding molecular calculations and atomic composition in chemical compounds.

Homework Statement


You are given a 250mg tablet of Vitamin C, C6H8O6. How many atoms are in the Vitamin C sample?


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?
