Question

A molecule of glucose is comprised of 6 atoms of carbon, 12 atoms of hydrogen, and 6

atoms of oxygen. What is the molar mass of glucose?

Answer 1

The molar mass of glucose (C6H12O6) is calculated by summing up the individual molar masses of its atoms, resulting in a molar mass of 180.16 grams per mole.

Step-by-step explanation:

The molar mass of a glucose molecule can be calculated by adding up the molar masses of its constituent atoms. Given that a molecule of glucose, which has the molecular formula C6H12O6, consists of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms, we need to find the molar mass of each type of atom and sum them up. The molar mass of carbon (C) is approximately 12 g/mol, hydrogen (H) is about 1 g/mol, and oxygen (O) is 16 g/mol.

Using these molar masses:

• Carbon: 6 atoms × 12 g/mol = 72 g/mol
• Hydrogen: 12 atoms × 1 g/mol = 12 g/mol
• Oxygen: 6 atoms × 16 g/mol = 96 g/mol

Adding these quantities together gives us the molar mass of glucose:

72 g/mol (carbon) + 12 g/mol (hydrogen) + 96 g/mol (oxygen) = 180.16 g/mol (glucose)

Therefore, the molar mass of glucose is 180.16 grams per mole.
