Hi there.
00:04
This question is asking us about carbon tetrachloride, which would be c -cl -4, based upon its name.
00:11
And we're told that the chlorine to carbon mass ratio is 11 .8 to 1.
00:16
What that means is that for every 11 .8 grams of chlorine, we will have one gram of carbon.
00:28
That's our 11 .8 to 1 ratio.
00:30
Well, if we have 41 grams of chlorine in a sample, we want to know what.
00:34
What mass of carbon we have.
00:37
So we can set this up as a proportion.
00:39
In other words, the 11 .8 grams of chlorine over this actual sample, which has 41 grams of chlorine, would be equal to 1 gram of carbon over the mass of carbon in this sample.
01:00
So that would be x grams of carbon.
01:03
All right, so now we just need to solve for x...
