Question

Based on these two statements, what conclusion could Dalton draw about the relative masses of oxygen and hydrogen atoms? How many times more massive is an oxygen atom than a hydrogen atom?

Answer 1

1- He reported that seven pounds of oxygen reacted with one pound of hydrogen to form water, but accurate modern experiments give eight pounds to one.

2- by determining the relative mass we will be able to determine for example that one element has twice the mass of a second element.

3- oxygen atoms were found to have a mass 16 times greater than the mass of hydrogen
