We are given the empirical formula of star in with ch, and we have the molar mass of 104 .1 .4 gramper mode.
00:10
What would be the number of hydrogen atom in 2 grammer sample? so first of all, we would like to file the molecular formula.
00:21
All right, so in order to find that we have to file the multiple number, and because for the different between molecular formula, the amplification formula is that they just differed by the molecule formula is a multiple of the empirical formula.
00:35
So we are going to look for the multiple, i also call n.
00:42
So we're going to take our motor mass, divided by the empirical motor mass.
00:51
So we are 104.
00:55
104 .14 gram per mole.
00:59
Okay, so let me write that.
01:01
104 .14 gram per mole.
01:05
Divided by the mass of ch, so it corresponding to roughly around 13 gram per mole...
