Explanation:
i just looked up a converter.
The answer is D: Saturated.
A saturated solution is one in which the exact maximum amount of solute has been dissolved. So, new solute will not dissolve in the solution. In contrast, an unsaturated solution can hold more solute, so if that option were correct, the crystal would have dissolved.
The other two terms are a bit more complicated. A supersaturated solution is one holding an amount of solute above the sustainable limit. Because of that, when more solute is added, the solution will immediately adjust, and some solute will come out of solution in a precipitate. Because the crystal isn't growing, we can eliminate this option.
A concentrated solution is one holding a relatively large amount of solute. However, you can have concentrated solutions that are saturated and unconcentrated (the word for this is dilute) solutions that aren't saturated. Therefore, we can say that because the crystal doesn't dissolve, this solution is saturated, but we can't say with certainty that it is concentrated.
Because the first three options are invalid, as described above, while the scenario does describe a saturated solution, D is the correct answer.
Answer:
[CO₂] = 375 ppm
Explanation:
We can determine the concentration in value of ppm
ppm = mass of solute (mg) / mass of solution (kg)
Solution: atmosphere
Solute: CO₂
We convert the mass of CO₂ from g to mg → 0.1875 g . 1000 mg / 1g = 187.5 mg
We convert the mass of the atmosphere from g to kg: 500 g . 1 kg/1000g = 0.500 kg
ppm = 187.5 mg / 0.500kg = 375

Answer : The amount of paper used by average United States citizen are, 210.47 kilograms.
Explanation : Given,
Total mass of paper used in the United States = 70 million tons
Total number of people in the United States = 301.6 million
First we have to calculate the amount of paper used by average United States citizen.
Now we have to convert amount of paper from tons to kilogram.
Conversion used :
1 ton = 907.185 kg
As, 1 ton = 907.185 kg
So, 0.232 ton = 
Therefore, the amount of paper used by average United States citizen are, 210.47 kilograms.
