NO, because if you add water, you will see the aqueous layer get larger. While the organic layer stays the same volume.

[spoiler]

urr... wouldn't it be better to take a sample from each layer, and add to a small sample of water, to see whether a separate layer forms?

because it's not easy to notice which phase changed in volume.

Thats why you keep on adding water until you notice one of the layers getting larger.
