Answer:
D. The mass ratio of oxygen to carbon in CO is twice the mass ratio of oxygen to carbon in CO2
Explanation:
Mass of Oxygen in 1 mole of substance = 16g
Mass of carbon in 1 mole of the same substance = 12g
Ratio of O : C = 12/16
= 1 : 0.75
Mass of oxygen in O2 = (16*2) = 32 g
Mass of carbon = 12 g
Mass ratio of O2 : C
= 32 : 12
= 12/32
= 1 : 0.375
From the calculations above, The mass ratio of oxygen to carbon in CO is twice the mass ratio of oxygen to carbon in CO2.
