Question

6. Find the approximate atomic mass of carbon dioxide. Give your answer in atomic mass units rounded to the nearest whole number.

Answer 1

To find the approximate atomic mass of carbon dioxide (CO2), we need to sum the atomic masses of one carbon atom and two oxygen atoms.

The atomic mass of carbon is approximately 12 atomic mass units (AMU), and the atomic mass of oxygen is approximately 16 AMU.

Therefore, the atomic mass of carbon dioxide is approximately 12 + (16 * 2) = 44 AMU.

Rounding to the nearest whole number, the approximate atomic mass of carbon dioxide is 44 AMU.

Answer 2

To calculate the approximate atomic mass of carbon dioxide (CO2), we need to consider the atomic masses of carbon (C) and oxygen (O) and their respective quantities in the molecule.

The atomic mass of carbon (C) is approximately 12 atomic mass units (amu), and the atomic mass of oxygen (O) is approximately 16 amu.

In carbon dioxide (CO2), there is one carbon atom and two oxygen atoms. Therefore, we can calculate the approximate atomic mass of carbon dioxide as:

Atomic mass of carbon dioxide = (Atomic mass of carbon) + 2 × (Atomic mass of oxygen)

= 12 amu + 2 × 16 amu

= 12 amu + 32 amu

= 44 amu

Hence, the approximate atomic mass of carbon dioxide is 44 amu.
