There are 2 oxygen atoms and 1 carbon atom in one carbon dioxide molecule. How many oxygen atoms are in 78 carbon dioxide molecules?

Given that we have 78 carbon dioxide molecules, we can find the total number of oxygen atoms by multiplying the number of molecules (78) by the number of oxygen atoms in each molecule (2):

[tex]\textsf{Number of oxygen atoms} = \textsf{78 molecules}\times\textsf{2 oxygen atoms/molecule}\\\\\textsf{Number of oxygen atoms} = \t156[/tex]

Therefore, there are 156 oxygen atoms in 78 carbon dioxide molecules.

!<Answer>!

In one carbon dioxide molecule, there are 2 oxygen atoms and 1 carbon atom. We want to find out how many oxygen atoms are in 78 carbon dioxide molecules.

To calculate the total number of oxygen atoms, we need to multiply the number of oxygen atoms in one carbon dioxide molecule by the number of carbon dioxide molecules.

Given that there are 2 oxygen atoms in one carbon dioxide molecule, we can set up the equation:

2 oxygen atoms/molecule * 78 molecules = ?

Multiplying the numbers:

2 * 78 = 156

Therefore, there are 156 oxygen atoms in 78 carbon dioxide molecules.

Please note that it is important to pay attention to the given information in the question and use that to calculate the desired result. In this case, knowing the number of oxygen atoms and carbon dioxide molecules allows us to determine the total number of oxygen atoms.
