Question

The atomic mass of an atom of carbon is 12, and the atomic mass of an atom of oxygen is 16. To produce CO, 16g of oxygen can be combined with 12g of carbon. To produce CO2, 32g of oxygen combine with 12g of carbon. The ratio of the masses of oxygen is: a)1:1 b)2:1 c)1:2 d)8:3

Answer 1

CO2, In this case the molecular formula tells you that for every atom of Carbon you need 2 of oxygen. So the molecular formula is 1:2
