Calculate the volume of co2 that will result from the interaction of 24 g carbon containing 20% impurities with o2.

We have a share of impurities. We can find first the mass of pure carbon and then the amount of pure carbon. To do this, we multiply the mass of carbon by the fraction of impurities. And then subtract the resulting number from the mass of carbon. We get 19.2 grams. Next, we divide by the molar mass of carbon, we find the amount of carbon, we get 1.6 mol. Carbon reacts with oxygen in a one-to-one ratio, therefore, the same mol of carbon dioxide is formed, that is, 1.6 mol. Then we multiply Molly by the molar volume (22.4 L / mol). And we get the answer 35.84L
