Take a hypothetical sample of exactly 100 grams of the solution.
(16g urea) / (60.06 g urea/mol) = 0.2664 mol urea
((100 g total) - (16g urea)) = 84.0 g H2O = 0.0840 kg H2O
(0.2664 mol) /0.0840 (kg) = 3.17143mol/kg = 3.18m urea
Answer:
Ur answer is C. Their average kinetic energy
Explanation:
In chemistry, we define the temperature of a substance as the average kinetic energy of all the atoms or molecules of that substance. Not all of the particles of a substance have the same kinetic energy. ... It is the average kinetic energy of the particles that thermometers measure and we record as the temperature.
The correct answer for the question that is being presented above is this one: "B) Temperature."
Here are the following choices:
A) all of these measurements are needed
B) Temperature
C) Molar Mass
D) Pressure
E) Mass
Answer:
If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration. ... Force is directly proportional to acceleration (force ~ acceleration) As force increases acceleration increases.
Tyson decided to exclude Pluto from the exhibits of planets because it displays the characteristics of an icy body rather than a planet.
