The simplest unit factor that relates the number of hydrogen in sucrose to the number of oxygens is 1 O atom/ 2 H atoms.
Sucrose is a diasaccharide having the formula; C12H22O11.
This implies that there are twenty two atoms of hydrogen and eleven atoms of oxygen in a molecule of sucrose.
This gives a ratio of 2 hydrogen atoms to one oxygen atom. Therefore, the simplest unit factor that relates the number of hydrogen in sucrose to the number of oxygens is 1 O atom/ 2 H atoms.
