Maltose is a disaccharide formed by a condensation reaction between glucose (C6H12O6) molecules - VCE - SSCE Chemistry - Question 18 - 2004 - Paper 1

Maltose consists of two glucose molecules. The molecular formula for glucose is C6H12O6. Thus, the formula for maltose is:

$C_{12}H_{22}O_{11}$

To calculate the molar mass, add the molar masses of all atoms in the formula:

• Carbon (C): 12 atoms × 12 g/mol = 144 g/mol
• Hydrogen (H): 22 atoms × 1 g/mol = 22 g/mol
• Oxygen (O): 11 atoms × 16 g/mol = 176 g/mol

Total molar mass: $144 + 22 + 176 = 342 ext{ g/mol}$

Therefore, the molar mass of maltose is 342 g mol⁻¹.
