<h2>Hello!</h2>
The answer is: 
<h2>Why?</h2>
First, we need to calculate the molecular weight of the acetone (CH3COCH3)
So,
Then,
Second, we need to calculate the mass of the acetone in the bottle
We need to remember that 
So,
Third, we need to calculate the number of moles:
Fourth, we need to calculate the number of atoms:
Remember, 
Therefore,
Have a nice day!
The computation for this problem is:
(1.55x10^4 / 1.0x10^3) x 19.8 mm Hg
= 15.5 x 19.88 mm Hg
= 308.14 mm Hg decrease
= 308.14 x 0.05 C = 15.407 deg C
deduct this amount to 100
100 – 15.407 = 84.593 C
ANSWER: 85 deg C (rounded to 2 significant figures)
A scientific theory is a well tested explanation of a natural phenomenon.
I'm not sure, but hope this helps.
5 HIO3 + 4 FeI2 + 25 HCl = 4 FeCl3 + 13 ICl + 15H2O
use of periodic table and look at the numbers in the corners
...I'm pretty sure...
