Question

a reference sample of a binary compound has a mass ratio of elements that is 3.43g cl: 1g p. listed are the empirical mass ratios of four different samples. indicate which sample that are of the same compound as the reference sample. 191.43g cl: 55.75g p 70.90g cl:41.29g p 106.35g cl: 30.97g p 53.2g cl: 15.5g p

Explanation:

Step1: Calculate ratio for reference sample

The reference ratio is $\frac{3.43}{1}=3.43$.

Step2: Calculate ratios for each option

For 191.43g Cl : 55.75g P, ratio is $\frac{191.43}{55.75}\approx3.43$.
For 70.90g Cl : 41.29g P, ratio is $\frac{70.90}{41.29}\approx1.72$.
For 106.35g Cl : 30.97g P, ratio is $\frac{106.35}{30.97}\approx3.43$.
For 53.2g Cl : 15.5g P, ratio is $\frac{53.2}{15.5}\approx3.43$.

Answer:

191.43g Cl : 55.75g P
106.35g Cl : 30.97g P
53.2g Cl : 15.5g P
