Glucose consists of 6 carbons, 12 hydrogens and 6 0xygens. Using rounded atomic weights: 6 * 12 = 72 from carbon 12 * 1 = 12 from hydrogen 6 * 16 = 96 from oxygen 72 + 12 + 96 = 180 The formula mass of glucose. read more
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. read more
The formula for glucose is C6H12O6. 6 C atoms X (12.01 amu / C atom) = 72.06 amu. 12 H atoms X (1.01 amu / H atom) = 12.12 amu. 6 O atoms X (16.00 amu / O atom) = 96.00 amu. read more
