B. All pure water samples include twice the mass of hydrogen than they do of oxygen.
This is because the chemical formula for water is H2O, meaning that there are twice as many hydrogen atoms as there are oxygen atoms in a water molecule. This aligns with the model of a water molecule showing an O with single bonds to 2 H's.
This is a model of a water molecule.
The model shows an O with single bonds to 2 H’s.
