Example 1

easy
Calculate the molar mass of glucose (C6H12O6\text{C}_6\text{H}_{12}\text{O}_6).

Solution

  1. 1
    C: 6×12.01=72.06 g/mol6 \times 12.01 = 72.06\,\text{g/mol}.
  2. 2
    H: 12×1.008=12.10 g/mol12 \times 1.008 = 12.10\,\text{g/mol}.
  3. 3
    O: 6×16.00=96.00 g/mol6 \times 16.00 = 96.00\,\text{g/mol}.
  4. 4
    Total: 72.06+12.10+96.00=180.16 g/mol72.06 + 12.10 + 96.00 = 180.16\,\text{g/mol}.

Answer

M=180.16 g/molM = 180.16\,\text{g/mol}
Molar mass is calculated by adding the atomic masses of all atoms in the formula. It tells us the mass of one mole of the substance.
