Okay, the empirical formula of the styrene is ch.
00:10
So the molar mass of the styrene is about 10, 104 .14 grams per more.
00:20
So what is the number the h atoms are present in 2 grams of sample of styrene? so first, we can calculate the mores of the c .h unit here.
00:31
So for c .h, the more mass is actually 14, 15, sorry.
00:43
It's about 15.
00:54
So in this case, you'll find actually the more mass, actually for the unit, right? look at more mass, it's actually stage 7 here.
01:05
Anyway, it's fine.
01:07
So first, we can calculate the more of the stage.
01:11
That's equal to, oh sorry, here is 13.
01:17
So you have eight units here.
01:20
So that's equal to the mass over the more mass...
