All right, guys, you're doing problem number 68 of chapter 3 in chemistry and molecular approach.
00:07
They want to sketching the mass of each sample.
00:10
So let's start out with a 4 .5 times 10 to the 25th ozone molecules.
00:24
So first we have to multiply that.
00:31
We have to divide it by avagadra's number.
00:33
So one mole over 6 .02 times 10 to the 23rd molecules.
00:45
And then we're going to convert it from moles to mass.
00:48
So then we divided by 48 grams per mole because there's 16 for every oxygen.
01:13
So that gives us 3 ,588 grams.
01:22
And next we have 9 .8 5 times 10 to the 19th molecules of c, cl2, cf2.
01:37
So again, we're going to multiply this, we're going to divide this by avogatra's number...
