Excellent! Because water is made up of \(2\) H atoms and \(1\) O atom, the mass of 1 molecule of water is \(\left(2 \times 1\right) + \left(16 \times 1\right) = 18 \, \mathrm{amu}\)
How much Hydrogen and how much Oxygen is there in one molecule of water?
  • \(2 \, \mathrm{amu}\) of Hydrogen and \(16 \, \mathrm{amu}\) of Oxygen
  • \(1 \, \mathrm{amu}\) of Hydrogen and \(16 \, \mathrm{amu}\) of Oxygen
  • \(2 \, \mathrm{amu}\) of Hydrogen and \(8 \, \mathrm{amu}\) of Oxygen
  • \(2 \, \mathrm{amu}\) of Hydrogen and \(1 \, \mathrm{amu}\) of Oxygen
