The mass ratio of carbon monoxide to carbon dioxide is 2:1, and the mass ratio of carbon element in them is 0______ The number ratio of molecules is______ ．

The mass ratio of carbon monoxide to carbon dioxide is 2:1, and the mass ratio of carbon element in them is 0______ The number ratio of molecules is______ ．

Suppose the mass of carbon monoxide is 2m, then the mass of carbon dioxide is m, and the molecular numbers are 2m28 and M44 respectively, then 2m28: M44 = 22:7, so the answer is: 22:7; 22:7

What is the mass of carbon in 10 grams of carbon monoxide and 10 grams of carbon dioxide?
A more carbon dioxide
B is equal
C more carbon monoxide
D can't compare

Let me tell you
If you want to see which is more, just look at the mass fraction of carbon
The relative mass of CO is 12 + 16 = 28 12 / 28 = 42.86%
The relative mass of CO2 is 12 + 32 = 44, 12 / 44 = 27.28%
C, of course

How many grams of carbon monoxide have the same mass as 22 grams of carbon dioxide?

Let x g of CO contain the same mass of carbon as 22 g of CO2
12x/28=22*12/44
The solution is: x = 14
A: the carbon content in 14g CO is the same as that in 22G CO2

What is the mass ratio of carbon in carbon monoxide and carbon dioxide with the same mass?

CO CO2
28 44
1 to calculate the relative molecular mass
2. Cross the relative molecular weight and do the measurement, that is, 44co 28co2, so that the mass of the substance is equal
The mass ratio of carbon element in 3 is 44:28 = 11:7
