Answer to Question #113203 in General Chemistry for Mohammed Al-fatlawi

Question

Glucose has the formula C6H12O6. What is the maximum mass of carbon that could be obtained from 200.00g of glucose?

Answer 1

Solution:

Glucose has the formula C₆H₁₂O₆.

This means every mole of glucose contains 6 moles of carbon.

To convert our mass of glucose to moles of glucose:

Moles of glucose = Mass of glucose / Molar mass of glucose

The molar mass of C₆H₁₂O₆ is 180.156 g/mol.

Moles of glucose = (200.00 g) / (180.156 g/mol) = 1.11 mol

One mole of glucose contains 6 moles of C, therefore:

Moles of carbon = (1.11 mol C₆H₁₂O₆) × (6 mol of C / 1 mol C₆H₁₂O₆) = 6.66 mol of carbon (C).

Now, using the molar mass of carbon (12.0107 g/mole) to calculate the total mass of carbon in the sample.

Mass of carbon = (12.0107 g/mol) × (6.66 mol) = 79.99 g = 80.00 g.

The maximum mass of carbon is 80.00 g.

Answer: 80.00 g is the maximum mass of carbon that could be obtained from 200.00g of glucose.
