In three experiments silver was converted to silver iodide. Samples of silver weighing 9.896, 10.440 and 9.528 were converted to 21.537g, 22.723g and 20.737g of silver iodide respectively. Show that these data illustrate the law of definite proportions.

Answer:
In any given chemical compound, the elements always combine in the same proportion with each other. This is the law of constant composition.
The law of constant composition says that, in any particular chemical compound, all samples of that compound will be made up of the same elements in the same proportion or ratio. For example, any water molecule is always made up of two hydrogen atoms and one oxygen atom in a 2:1 ratio. If we look at the relative masses of oxygen and hydrogen in a water molecule, we see that 94% of the mass of a water molecule is accounted for by oxygen and the remaining 6% is the mass of hydrogen. This mass proportion will be the same for any water molecule.
Answer:
The dark reactions occur in the stroma. or, in words: carbon dioixde + water + light energy ---> glucose + oxygen + water OK, onward .... ... The oxygen is released from the plant into the air. ATP & NADPH2 are energy molecules
