What is the molecular formula of each compound?

(a) Empirical formula $\mathrm{CH}_{2}(M=42.08 \mathrm{g} / \mathrm{mol})$

(b) Empirical formula $\mathrm{NH}_{2}(\mathscr{M}=32.05 \mathrm{g} / \mathrm{mol})$

(c) Empirical formula $\mathrm{NO}_{2}(\mathscr{M}=92.02 \mathrm{g} / \mathrm{mol})$

(d) Empirical formula CHN $(M=135.14 \mathrm{g} / \mathrm{mol})$

a) molecular formula= $\mathrm{C}_{3} \mathrm{H}_{6}$

b) molecular formula $=\mathrm{N}_{2} \mathrm{H}_{4}$

c) molecular formula= $\mathrm{N}_{2} \mathrm{O}_{4}$

d) molecular formula= $\mathrm{C}_{5} \mathrm{N}_{5} \mathrm{H}_{5}$

So we have to found Walker foreigner from the gifting empirical formula. So for a the every foreigner we research too. And the Marco Fuller before two point. Oh, wait. The different mentioned Morgan Foreigner and broke a foreigner. Is that Michael Farmer? Just a multiple off the empirical phoner. So therefore it will be seen. I can Can we apply to the empirical? Um, with a mask. So from here, we can find the entry code for the mass Will be You're free around our 14 severe. We have 12 plus to travel because someone in carbon true Well, because fun into hydrogen. So what we're going to do is that we take our overall more the mass divided by our will amass off the empirical formula. So 42.0. H Divided by 14. Well, wolf, they have fleas 0.15 0 so we know that of the multiple would be if you point. Oh, so ah, it will be our microphone every three times for it. And fickle fauna. So, um, the actual market fauna will be C three a six. So we just need more by the whole thing by three. Okay, So same thing we're going to apply to the west of the question. So the empirical foreign formula an itch too will be, Ah, 16. So we're going to Ah, again to our more killer off the mother mass divide by 16. And how we should be able to find that the mobile will be roughly around too. So that's why we were on to H four at the Markkula formula. Okay. And then for an 02 we have 14 for 16 times too. And there were 92 point over to d O by 46. So what flee the multiple would be too. So we have into 04 So just remind you did that this one will ah, them blow them massive them people phone every before he Quimper. No. Okay, so ah, for park sti. So we just need to father again. Don't. But more the mass off the empirical falling arse over here for a C h and then Ah, nitrogen. So we're trying a river for around 27 grand for move, and then the overall mass will be one for 5114 day went by 27. So we were roughly around five times more than ethical formula, So we have C five, h five and five for the market of formula.
