The oxidation of glucose can result in several products. you perform combustion analysis on a 2.750 g sample that resulted from the oxidation of glucose and obtain 3.702 g co2 and 1.514 g h2o. how many carbon atoms are in the empirical formula of the isolated sample? (assume no other products present from the oxidation of glucose.)]

There is 1 carbon atom in the empirical formula.

Explanation:

First, let's use the given mass of CO₂ to calculate the moles of C, which will be the same amount of C moles present in the sample:

Then with the mass of H₂O we calculate the moles of H:

Now we calculate the mass of C, H in the sample, in order to calculate the mass of O, which is calculated by substracting the mass of C and H from the total mass:

Then we convert g O to mol O

C ⇒ 0.0841 mol C

H ⇒ 0.1682 mol H

O ⇒ 0.0983 mol O

Now we divide those values by the lowest among them:

So the empirical formula is CH₂O

There is 1 carbon atom in the empirical formula.

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.
