What is the molar mass of sucrose (C₁₂H₂₂O₁₁)?

Question

Quizplus · Accepted Answer

The molar mass of sucrose is calculated by adding up the atomic masses of all the atoms in one molecule of sucrose. The molecular formula of sucrose includes 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. Using the periodic table to find the atomic masses of each element and multiplying the subscripts by those values, we get:

12 x 12.01 g/mol for carbon = 144.12 g/mol
22 x 1.01 g/mol for hydrogen = 22.22 g/mol
11 x 16.00 g/mol for oxygen = 176.00 g/mol

Adding these values together gives us a molar mass of 342.34 g/mol, which we can round to 342 g/mol (D).
