To answer, you need the formula: H 2 O (2 H atoms for 1 O atom) (11.1)/2 = 5.55 → (88.9)/5.55 = 16.0...If water is 88.9% O, 11.1% H, what is the atomic mass of O in terms of H (if you assume H is 1.00)? To answer, you need the formula: H 2 O (2 H atoms for 1 O atom) (11.1)/2 = 5.55 → (88.9)/5.55 = 16.0 (this is the atomic weight of O, assuming H is ~1) Gay-Lussac's law describes how increasing the temperature of a gas with a fixed volume and a constant number of "particles" will result in a similar increase in the pressure of the gas, and vice versa.

It highlights the development of atomic theory from ancient Greek thought to modern science, discussing key figures like Democritus, Robert Boyle, Joseph Priestley, and Antoine Lavoisier. It explains fundamental chemical laws, Dalton's atomic theory, Avogadro's hypothesis, and the law of multiple proportions.
