Which French chemist measured alcohol content and co-discovered that water is composed of two parts hydrogen and one part oxygen?

Explanation:
Gas-volume measurements reveal the true formula of water. Joseph Louis Gay-Lussac pioneered precise quantitative work on how gases combine, showing that reactions occur in simple whole-number volume ratios. In his experiments forming water from hydrogen and oxygen, he observed that two volumes of hydrogen combine with one volume of oxygen to produce water, which points to the empirical formula H2O. His careful, accurate measurements extended to fermentation studies as well, including assessing alcohol content, demonstrating his skill with quantitative chemistry. This combination of exact measurement and the clear gas-volume ratio is why he is the best fit for the description.
