The answer i got was 2.55 M KOH
Mole<span>: the amount of a substance that contains 6.02 x </span>10<span>. 23 respective particles of that substance. Avogadro's number: 6.02 x </span>10<span>. 23. Molar Mass: the mass of one </span>mole<span> of an element. CONVERSION FACTORS: 1 </span>mole<span> = 6.02 x </span>10<span>. 23 </span>atoms<span> 1 </span>mole<span> = </span>atomic<span> mass (g). Try: 1. How </span>many atoms<span> are in 6.5</span>moles<span> of zinc</span>
The boiling point of oxygen is higher than nitrogen's boiling
The reason the boiling point of O2 is higher is not because of increased van der Waals interactions, but simple physics. The mass of a molecule of O2 is greater than that of a molecule of N2, so the molecule of O2 traveling at a speed sufficient to break out of the liquid phase has a greater kinetic energy than an analogous N2 molecule.
The net effect is that more energy must be distributed throughout a sample of O2 to achieve a given vapor pressure (in this case equal to atmospheric pressure) than for a sample of N2. More energy means greater temperature.
Answer: Option (e) is the correct answer.
Explanation:
According to Henry's Law, mass of a gas which will dissolve into a solution is directly proportional to the partial pressure of that gas above the solution.
Mathematically, C = 
where, 
= Henry's constant
P = partial pressure
Since, concentration is directly proportional to partial pressure of a gas. Hence, more is the partial pressure more will be the number of molecules present in the liquid.
Thus, we can conclude that the statement there are twice as many gas molecules in the liquid, is true.
