This question appears incomplete
Explanation:
However, it should be noted that addition of soluble salts generally lowers the freezing point of water hence after the addition, water will no longer freeze at 0°C but lower.
Soluble salts tend to form more ions in water, it is these ions that are responsible for interfering with the hydrogen bonds hence lowering the freezing. Thus, (since each bag are of the same weight) <u>the bag that contains the salt that ionizes more in water will lower the freezing point by the greatest amount</u>.
NOTE: Different weight of the salts could lead to more ions been formed in the water by some salts as against the other.

Problem Type: mass - mass
(I've done this before and my teacher gave that answer)
Answer:
= 2.94 atm
Explanation:
The total pressure () in the container is given by:
The pressure of the oxygen (
) and the pressure of the helium (
) can be calculated using the ideal gas law:
<u>Where</u>:
V: is the volume = 25.0 L
n: is the number of moles of the gases
R: is the gas constant = 0.082 Latm/(Kmol)
T: is the temperature = 298 K
First, we need to find the number of moles of the oxygen and the helium:
Where m is the mass of the gas and M is the molar mass
And the number of moles of helium is:
Now, we can find the pressure of the oxygen and the pressure of the helium:
Finally, the total pressure in the container is:
Therefore, the total pressure in the container is 2.94 atm.
I hope it helps you!
