Law of Multiple Proportions

[Bashyboy]

1. The problem statement, all variables and given/known data
The Problem goes as follows:

Palladium forms three different compounds with sulfur. The mass of sulfur per gram of palladium in each compound is listed below:

Compound Grams S per Gram Pd
A 0.603
B 0.301
C 0.151

Show that these masses are consistent with the law of multiple proportions.

2. Relevant equations



3. The attempt at a solution
I feel as though this is a trick question: when I venture to find the ratio between C and B I come up with 2; but, when I multiple 3 by .151, I don't come out with .603. As I type this I am beginning to feel that I don't quite understand the ratio. Could some explain to me if this problem follows the Law of Multiple proportion; and, if so, how? And also, why doesn't multiplying .151 by 3 yield .603? Thank you

Compound Grams S per Gram Pd
A 0.603
B 0.301
C 0.151

Notice how each of the three ratios of S to Pd is different. A is two times B, and B is two times C.

why doesn't multiplying .151 by 3 yield .603?

Because it yields 0.453?

Seriously: law of multiple proportions says that ratios are small integers, it doesn't say they have to be consecutive.

Thank you both.
