Question

This model is a model of a water molecule

Oxygen hydrogen hydrogen molecules of a water model

Oxygen 16 Mass hydrogen one Mass

Which evidence can be used to determine that this is an accurate model of the water molecule?

All pure water samples include half the mass of then they do of oxygen
All pure water samples include twice the mass of hydrogen than they do oxygen
All pure water samples include 8 times the mass of oxygen then they do hydrogen
All of your water samples include 16 times the mass of oxygen then they do hydrogen

GPT 3.5
The correct evidence to determine that this is an accurate model of the water molecule is:

All pure water samples include twice the mass of hydrogen than they do of oxygen.

In the water molecule, there are two hydrogen atoms and one oxygen atom. The mass of one oxygen atom is 16, and the mass of one hydrogen atom is 1. Therefore, in a water molecule, the total mass of hydrogen atoms (2) is twice the mass of the oxygen atom (1).
