Question

A chemical formula is made up of carbon and oxygen. they have 27% and 73% respectively.

A.what is the empirical formula of the chemical substance?

B.name the compound you identified in A above.​

Answer 1

The empirical formula of the compound is CO₂, and the compound identified is carbon dioxide.

Step-by-step explanation:

The empirical formula of a compound can be determined by analyzing the relative amounts of each element in the compound. In this case, the compound is made up of carbon and oxygen, with 27% carbon and 73% oxygen. To find the empirical formula, we convert these percentages to moles and then find the ratio of the number of atoms. In this case, the ratio is 1 carbon atom to 2 oxygen atoms, so the empirical formula is CO₂.

The compound identified in part A is called carbon dioxide, which is a commonly known compound formed by the combination of carbon and oxygen.

Answer 2

A. CO₂

B. carbon dioxide

Step-by-step explanation:

To determine the empirical formula of a compound, we need to follow a series of steps.

Step 1: Divide each mass percent by the atomic mass of the element

C: 27/12.01 = 2.25

O: 73/16.00 = 4.56

Step 2: Divide all the numbers by the smallest one, i.e., 2.25

C: 2.25/2.25 = 1

O: 4.56/2.25 ≈ 2

The empirical formula of the compound is CO₂. The name of this compound is carbon dioxide.
