Question

Estimate the molecular mass of the glucose (${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$) molecule.

Answer 1

Explanation

• Glucose molecule
• Glucose is a simple sugar with six carbon atoms and one aldehyde group. This monosaccharide has a chemical formula ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$

Structure of Glucose – ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$

• The molecular mass of glucose
• Chemical formula =${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$
• The atomic weight of Carbon = 12
• Glucose contains 6 carbon atoms
• Hence$6\times 12=72$
• The atomic weight of Hydrogen is 1
• Glucose contains 12 Hydrogen atoms
• Hence $1\times 12=12$
• The atomic weight of Oxygen is 16
• Glucose contains 6 oxygen atoms
• Hence $6\times 16=96$
• The molecular mass of glucose= Sum of the atomic weight of all-atom
• The atomic weight of 6 Carbon atoms + Atomic weight of 12 Hydrogen atoms + Atomic weight of 6 Oxygen atoms

$=72+12+96=180$

Therefore, the molecular mass of the glucose (${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$) molecule is 180 g/mol.
