C
This is because 10+5=15
15/45=0.3
Answer:
16 g/mol
Explanation:
In CO2, it means we have 1 mole of carbon and 2 moles of oxygen.
However, we want to find the molar mass of just a single mole of oxygen.
Now, from tables of values of elements in electronic configuration, the molar mass of oxygen is usually approximately 16 g/mol.
In essence the molar mass is simply the atomic mass in g/mol
They are in order according to their atomic number, so the position should tell you the atomic number.
The answer is "Incidents"
The accepted model of the atom was changed.
