Question

A sample contains 1.3 moles of carbon, 1.3 moles of hydrogen, and 13.0 moles ofoxygen. Find the empirical formula. What is the subscript for oxygen?

Answer 1

`\begin{gathered} \text{Empirical formula = CHO}_(10) \\ The\text{ subscript for oxygen is 10} \end{gathered}`

Step-by-step explanation:

Given information

The moles of carbon = 1.3 moles

The moles of hydrogen = 1.3 moles

The moles of oxygen = 13.0 moles

From the given data above, it is easy to determine the empirical formula of the compound

Since the moles of each element is given in the question provided, then we can now find the empirical formula by finding the mole ratio of the elements

To find the mole ratio, we will need to divide the moles by the smallest number of moles.

Therefore, the empirical formula of the compound is given below as

`\text{Empirical formula = CHO}_(10)`

From the empirical formula above, the subscript for oxygen is 10
