<p>"A series of whole number ratios can be formed by comparing amount of a second element compared to 1 g of the other element in a compound which contains the 2 elements."</p>
<p>Question: Does this law imply that a whole number ratio can be invoked from comparison of the series of compounds formed by X and Y based on X set at 1 g or Y set at 1 g or both? Is it both sometimes but not always?</p>
<p>I think it's the latter because say you found that in compounds formed by X and Y, a series of ratios can be found: 5:4:3:2:1, this means that taking the inverse of these ratios would also yield whole number ratios when comparing the new series' ratio? </p>
<p>So I would like some advice on how to interpret this law correctly.</p>
