Purpose of the Photoelectric Effect

Why is it important to know what the photoelectric effect is? Is it just supposed to explain that light doesn't act only as a wave but as a particle too?

Re: Assuming Sample Size

Oh okay. I think I understand. So, I can assume the sample size is any number just as long as the ratio of the components is the same?

Assuming Sample Size

Why are we able to assume that the sample size is 100g to go from mass percentage composition to grams? I understand why we do it but I don't fully understand how we are actually able to do that? In other words, why is it okay to assume that the sample size is 100g?
