Question

How many carbon dioxide molecules would you have if you had a total of six oxygen atoms? What would be the total atomic mass?

Options:
A) 2 carbon dioxide molecules, 88 g/mol
B) 2 carbon dioxide molecules, 66 g/mol
C) 3 carbon dioxide molecules, 88 g/mol
D) 3 carbon dioxide molecules, 132 g/mol

Answer 1

If you have 6 oxygen atoms, you would need 3 molecules of carbon dioxide. The total atomic mass of 1 molecule of carbon dioxide is 44.01 g/mol.

Step-by-step explanation:

To determine the number of carbon dioxide (CO2) molecules you would have if you had a total of six oxygen atoms, you need to consider the molecular formula of carbon dioxide (CO2). One molecule of carbon dioxide consists of 1 atom of carbon and 2 atoms of oxygen. Therefore, if you have 6 oxygen atoms, you would need 3 molecules of carbon dioxide.

The total atomic mass can be calculated by adding together the masses of 1 atom of carbon and 2 atoms of oxygen. The molar mass of carbon is 12.01 g/mol, and the molar mass of oxygen is 16.00 g/mol. So, the total atomic mass of 1 molecule of carbon dioxide would be 12.01 g/mol + 2(16.00 g/mol), which equals 44.01 g/mol.
