(4)KBr(aq)
Explanation:
A mixture is an impure substance made up of two or more substances that are joined together. Their composition is indefinite and not easily represented by a simple chemical formula.
KBr is a mixture because it made up of an aqueous solution of KBr. This suggests that the substance KBr is placed inside water.
Here, we have two states of matter which is the solid and the liquid coming together.
As with both mixtures, they can be separated by physical means, KBr aqueous solution can also be done this way.

Answer:
The mass is
Explanation:
From the question we are told that
The Henry's Law constant is
The volume of water is
The partial pressure is
The temperature is
Henry's law is mathematically represented as
Where C is the concentration of sulfur hexafluoride(SP)
substituting value
The number of moles of SP is mathematically represented as
substituting value
The mass of SP that dissolved is
Where Z is the molar mass of SP which has a constant value of
So
