What is the empirical formula if you have 134g Fe, 76.9g S and 115g O?

The answer to your question is  FeSO₃

Explanation:

Data

Fe = 134 g

S = 76.9 g

O = 115 g

Process

1.- Convert the grams to moles for each element

For Fe

                        56 g of Fe 1 mol

                       134 g of Fe  x

                        x = (134 x 1) / 56

                        x =  134/56

                        x = 2.39 moles

For S

                        32 g of S 1 mol

                        76.9 g of S  x

                         x = (76.8 x  1) / 32

                         x = 2.4 moles

For O

                        16 g of O 1 mol

                       115 g of O  x

                         x = (115 x 1)/ 16

                         x = 7.18 moles

2.- Divide by the lowest number of moles

Fe    = 2.39/2.39 = 1

S      = 2.4/2.39 = 1

O     = 7.18/2.39  = 3

3.- Write the empirical formula

                            FeSO₃

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
