Left Panel
It's half right, but the pressure could be anything if the ice water is anywhere but on the sea shore. Hold your nose and pick B as you have.
Second from left
The mass of the glucose is 6*12 + 12*1 + 6*16 = 180
1.3 moles of this sugar = 234 grams
The total mass of the sugar and the water is given as 276.
The % = (234 / 276) * 100 = 85% rounded. So you made the right choice again.
2nd from the right
You've got the right answer. Just for fun I'm going to eliminate all the others.
We have no idea what the structure looks like. It might have a double bond somewhere or not. We don't know anything about that. A is incorrect.
B is the answer.
C No only the periodic table gives the mass of each compound.
D It comes nowhere's near giving all the atoms in the compound. D is just taking up space.
E is subtly wrong. C4H10 could be one of the choices this formula describes. It could also be C6H15. There are no end of choices.
Right Panel
I'm not getting your answers for the ones you have chosen. Both come in at 47% which I think is too far away. I'll leave you to check the other three, but just eye balling it, I don't think there's an answer that works. I am not working with a calculator. It does me a lot of good being at home. I'll quickly check again. The only one that works is C2H5OH
C2H5OH = 2*12 + 6*1 + 1*16 =46
24/46 = 52% about.
