Answer:
<u><em></em></u>
- <u><em>Concentrated</em></u>
Explanation:
Concentration measures the amount of solute in a solution. There are many expressions of concentration. Some of then are percentage (mass/mass, volume/mass, volume/volume), molarity, molality, mole fraction, among others.
When a solution has a high concentration it is said that it is <em>concentrated; </em>when a solution has a low concentration is is said that is is diluted.
Concentrated solutions expressed in percentage typically have about 80 - 90% (or more) of solute.
Diluted solutions expressed in percentage, tipylcally have about 10% - 20% or less.
But they are not fixed limits. You might say that a 85% solution is concentrated. Acids at 75 % sure are concentrated.
Hence, a 93.3% solution is concentrated, definitely.

Answer:
29.232 l
Explanation:
6.023x10^23 mole of nitrogen =22.4 l
7.83×10^23 mole of nitrogen =
22.4/(6.023×10^23)×7.83×10^23
=29.232 l
Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.
Answer:
Explanation:
The question is not completely clear because some missing parts or grammar (syntax) errors.
Interpreting it, the question is <em>what is the Kelvin temperatue of the air in a tire, when the pressure in the tire has increased to 225 kPa, if the initial conditions of the air inside the tire were 188kPa of pressure and a temperature of 32ºC.</em>
To solve this, you can assume constant volume and use the law of Gay-Lussac for ideal gases:
That equation works with absolute temperatures, i.e. Kelvin.
- 32ºC = 32 + 273.15 K = 305.15K
Then solve for T₂, substitute and compute:
