Use the specific heat equation for each one:
Q = mCT
m is mass
T is change in temp
C is spec heat
You will not only have to calculate three different specific heats, but also do the heat of vaporization and heat of fusion.
Heat of vaporization is 3.33 * 10^5 J/Kg
Heat of Fusion is 2.26 * 10^6 J/Kg
You’ll want to make sure all your units match. So change all Kg to g (or g to Kg)
-20 to 0 = mC(Ice)T
Melt ice (fusion) = m(heat of fusion)
0 to 100 = mC(Water)T
Boil (Vaporization) = m(heat of vaporization)
100 to 250 = mC(Steam)T
Then add each one together
Answer: Mass of the condensed vapor is 21.35 grams.
Explanation: As a gas, the Ideal Gas Law can be used to determine how many mols there are in the flask on the conditions described in question.
Temperature in K: 273 + 99.3 = 372.4K
Pressure in mmHg: P = 760.5 mmHg
Volume in L: V = 496.3.
= 0.5 L
Universal Constant of Gases in mmHg: R = 62.36 L.mmHg.K⁻¹.mol⁻¹
PV = nRT
n = 
n = 
n = 0.1625
To determine the mass in grams:
n = 
m = nM
m = 0.1625.131.4
m = 21.35
On the conditions cited above, there are <u>21.35 grams</u> of the unknown condensed vapor
I'm pretty sure it's Ca2+ and F- because Ionic bonds are metals and nonmetals
