Calculate the moles of 12.354 grams of C6H12O6

To calculate the moles of a substance, you need to use its molar mass.

1. Determine the molar mass of C6H12O6 (glucose):

   • C (carbon) has a molar mass of 12.01 g/mol
   • H (hydrogen) has a molar mass of 1.01 g/mol
   • O (oxygen) has a molar mass of 16.00 g/mol

2. Multiply the molar mass of each element by the number of atoms in the formula:

   • C: 6 atoms x 12.01 g/mol = 72.06 g/mol
   • H: 12 atoms x 1.01 g/mol = 12.12 g/mol
   • O: 6 atoms x 16.00 g/mol = 96.00 g/mol

3. Add up the molar masses of each element:

   • 72.06 g/mol + 12.12 g/mol + 96.00 g/mol = 180.18 g/mol

4. Use the formula: moles = mass / molar mass

   • moles = 12.354 g / 180.18 g/mol

5. Calculate the moles:

   • moles = 0.0685 mol

Therefore, there are approximately 0.0685 moles of C6H12O6 in 12.354 grams.
