Okay, so we're going to start with our two moles of c2h6.
00:09
And we can convert this to molecules by multiplying by 6 .02 times 10 to the 23rd.
00:23
And this is going to give you 1 .2 times 10 to the 24th.
00:35
Do the same thing with all of the other substances.
00:39
We have 7 .02s, 4 co2s, and 6 h2os.
00:43
So we'll go to the oxygen next.
00:55
So you're going to get 4 .2 times 10 to the 24th.
01:06
Then you're going to take your co2, and you've got four moles of co2, 6 .02 times 10 to the 23rd.
01:28
That's going to give you 2 .4 times 10 to the 24th.
01:35
And then you've got six moles of h2o.
02:02
So now we can fill this in with 2 .4 times 10 to the 24th, and then 3 .6 times 10 to the 24th here.
02:13
Okay.
02:14
Now to convert to atoms, what we're going to do is we're going to take what we got in molecules, and then you're going to multiply this c2h6.
02:27
By eight because there are eight atoms in it.
02:31
So this is gonna be 9 .632 times 10 to the 24th atoms...
