In this problem, you're told that you have an empirical formula of c -h2o.
00:08
But you're told that for your molecular formula, you have 60 amu, which for our purposes here, we think of this as 60 grams per mole.
00:22
So what we want to do, in order to figure out our molecular formula, we're going to find the mass of our empirical formula first.
00:33
So here we use atomic masses.
00:36
Carbon is 12 grams per mole.
00:39
Each hydrogen is one.
00:43
And oxygen is 16.
00:45
And we just add these up to get 30.
00:49
And that's grams per mole.
00:51
And remember that an empirical formula is just the most simplified version of your formula you can get.
00:58
So our molecular formulas are all going to be some multiple of this.
01:01
So you can think of multiple and applying it by, let's say, n...
