The table shows the relative atomic masses of some common elements. Use this information to work out the relative formula mass of carbon dioxide.

1. ### Break Down the Problem

To calculate the relative formula mass of carbon dioxide (CO₂), we need to identify the atomic masses of carbon and oxygen from the table and then apply them to the formula of carbon dioxide.

2. ### Relevant Concepts

The formula for carbon dioxide is $\text{CO}_2$, which means it contains one carbon atom and two oxygen atoms. The relative formula mass (RFM) can be calculated using the following expression:

$\text{RFM} = (\text{Number of C atoms} \times \text{Atomic mass of C}) + (\text{Number of O atoms} \times \text{Atomic mass of O})$

3. ### Analysis and Detail

Assuming the atomic masses based on typical values:

• Atomic mass of Carbon (C) = 12
• Atomic mass of Oxygen (O) = 16

Using the formula:

$\text{RFM} = (1 \times 12) + (2 \times 16)$

Calculating each part:

• Contribution from Carbon: $1 \times 12 = 12$
• Contribution from Oxygen: $2 \times 16 = 32$

Now, summing both contributions:

$\text{RFM} = 12 + 32 = 44$

4. ### Verify and Summarize

We have calculated the RFM of carbon dioxide from its constituent elements. The atomic masses used are standard, and the calculations confirm that the total sum is accurate.

Final Answer

The relative formula mass of carbon dioxide (CO₂) is 44.
