This question asks us to verify through three different carbon oxygen compounds, the law of multiple proportions, which in layman's terms basically says if we have compounds that can be formed, multiple compounds that can be formed by the same two atoms and different combinations of them, the ratios of their masses will always be whole numbers.
00:26
So let's look for example at carbon monoxide here.
00:33
If we look at the masses and the mass of carbon first, it's molar mass is 12 grams from all.
00:39
Oxygen, 16 grams from all.
00:41
If you take a ratio of these two and simplify 12 over 16, it's a 3 to 4 ratio, or if we want to write it this way, we could write it this way as well, but it's a whole number ratio.
00:57
Three, we could say three grams of carbon for every four grams of oxygen in this compound.
01:05
Or if we simplified it even more and wanted to look at this as per gram of oxygen, we could say 0 .75 grams of carbon for every one gram of oxygen in this compound.
01:20
And so, again, a whole number ratio is going to be present anytime we have a coupling of carbon and oxygen in any of these compounds because they verify the law of multiple proportions in the way that they behave in forming compounds...
