Answer:
1.14 M
Explanation:
grams/molar mass = ans. / volume
317/110.98=2.86/2.50=1.14 M

Answer : the system the scientist is studying consists of the car, the humid garage and Air
Explanation:
In order to find the system, the scientist is studying, we need to take a look at what happens to different parts of a car in a humid garage.
Majority parts of the car are made of iron. In humid garage, there is moisture ( Water vapors) in the air. When iron comes in contact with oxygen from air and moisture, corrosion of iron begins. Corrosion is a reaction of iron with oxygen in presence of water which produces iron oxide which is known as rust.
Therefore we can write down the equation for the reaction that is occurring in a humid garage
Iron ( Parts of car) + Water ( humid garage) + Air ( oxygen) ⇒ Iron oxide ( Rust)
Therefore the system the scientist is studying consists of the car, the humid garage and Air

Answer
is: 1) ccl4, kb = 29.9°c/m, carbon tetrachloride has the greatest boiling point
elevation.
The boiling point elevation is directly
proportional to the molality of the solution according to the
equation: ΔTb = Kb · b.
<span>
ΔTb - the boiling point
elevation.
Kb - the ebullioscopic
constant.
b - molality of the solution.
So the highest boiling poing elevation will be for solution with highest ebullioscopic constant because molality is the same.</span>
