If the mass ratio of K to F in a compound is 2.06:1, how many grams of F are needed to react with 101g of K?

Mass of F to react with 101 g of K = 49.03 g

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison

With this law, we can calculate how many grams an element is needed to make a compound with a certain mass, as desired

The mass of compounding compounds can also be calculated.

For example, the mass ratio of oxygen (O) and hydrogen (H) elements in H₂O remains at 8: 1. So if you know the amount of mass of oxygen you can know the amount of hydrogen and water mass.

The mass ratio of K to F in a compound is 2.06:1, so the mass of F to react with 101 g of K :
