Question

1. how many carbon dioxide molecules would you have if you had a total of six oxygen atoms? what would be the total atomic mass? 5. how many penicillin molecules would you have if you had a total of 36 hydrogen atoms? what would be the total atomic mass?

Explanation:

Step1: Determine number of carbon - dioxide molecules

In one carbon - dioxide ($CO_2$) molecule, there are 2 oxygen atoms. If there are 6 oxygen atoms, the number of $CO_2$ molecules $n_{CO_2}=\frac{6}{2}=3$.

Step2: Calculate total atomic mass of carbon - dioxide

The atomic mass of carbon ($C$) is approximately 12 g/mol and the atomic mass of oxygen ($O$) is approximately 16 g/mol. The molar mass of $CO_2$ is $M = 12+2\times16=44$ g/mol. For 3 moles of $CO_2$, the total atomic mass $m = 3\times44 = 132$ g.

Step3: Determine number of penicillin molecules (assuming a general penicillin formula with a certain number of hydrogen atoms)

Let's assume a penicillin formula with $x$ hydrogen atoms per molecule. Without knowing the exact formula of penicillin used here, if we assume a simple case where there are 16 hydrogen atoms in a penicillin molecule (for illustration purposes, actual number varies by type of penicillin). The number of penicillin molecules $n_{penicillin}=\frac{36}{16}= 2.25$ (in a real - world scenario, we need the correct molecular formula to get an accurate whole - number result).

Step4: Calculate total atomic mass of penicillin

Since we don't know the exact formula, we can't accurately calculate the molar mass. But if we assume a molar mass $M_{penicillin}$ (say for a simple model penicillin with molar mass 334 g/mol, this is just an example value), the total atomic mass $m_{penicillin}=2.25\times M_{penicillin}$.

Answer:

For carbon - dioxide: 3 molecules, total atomic mass is 132 g.
For penicillin: 2.25 molecules (assuming 16 H atoms per molecule), total atomic mass depends on the actual molar mass of the penicillin formula used.
