75 moles Five carbon atoms, twelve hydrogen atoms, and one oxygen atom make up each molecule of methyl tert-butyl ether, which has the formula (CH3)3COCH3.
Consequently, there is one mole of oxygen for every twelve moles of hydrogen. Therefore, to find the amount of oxygen in moles, simply divide the number of moles of hydrogen by 12. 69.0 / 12 = 5.75 Because of this, the sample contains 5.75 moles of oxygen.
The International System of Units uses the term "mole" (symbol: mol) to denote the amount of a substance (SI).
