Question

Answer the following questions about the conversion of the sucrose (C₁₂H₂₂O₁₁) in sugarcane to ethanol (C₂H₆O) and CO2 according to the following unbalanced equation. In this way sugarcane is used as a renewable source of ethanol, which is used as a fuel additive in gasoline.

C₁₂H₂₂O₁₁(s) + H₂O(l) → C₂H₆O(l) + CO₂(g)

What is the molar mass of sucrose?

Answer 1

The molar mass of sucrose (C₁₂H₂₂O₁₁) can be calculated by summing up the atomic masses of all the atoms in the molecule.

Step-by-step explanation:

The molar mass of sucrose (C₁₂H₂₂O₁₁) can be calculated by summing up the atomic masses of all the atoms in the molecule. The atomic masses can be found on the periodic table of elements. The molar mass of carbon (C) is 12.01 g/mol, the molar mass of hydrogen (H) is 1.008 g/mol, and the molar mass of oxygen (O) is 16.00 g/mol.

To calculate the molar mass of sucrose, we multiply the number of atoms of each element by their respective molar masses and sum them up:

Molar mass of C₁₂H₂₂O₁₁ = (12.01 g/mol x 12) + (1.008 g/mol x 22) + (16.00 g/mol x 11)
