The question is incomplete, the complete question is;
In a laboratory experiment, students synthesized a new compound and found that when 12.23 grams of the compound were dissolved to make 228.1 mL of a benzene solution, the osmotic pressure generated was 4.55 atm at 298 K. The compound was also found to be non-volatile and a non-electrolyte. What is the molecular weight they determined for this compound?
Answer:
287.76 g/mol
Explanation:
From;
π
=
M
R
T
M = molarity
R= gas constant
T = temperature
number of moles = π * volume/RT
number of moles = 4.55 * 228.1/1000/0.082 * 298
number of moles = 1.037855/24.436
number of moles = 0.0425 moles
Molar mass = mass/number of moles
Molar mass = 12.23 grams/0.0425 moles
Molar mass = 287.76 g/mol
The Nuremberg War Crimes trials established the international legal precedent that individuals who violate human rights can be held responsible for their actions. The correct option in regards to all the options given in the question is option "2".
The Nuremberg trials were held
against the Germans by the Allied forces against the war crimes done by the
Germans during World War II. Many of the allied countries were in favor of
killing the war criminals before any trial, but ultimately the trial was held
and the criminals were either hanged to death of were killed by the firing
squad.
The answer for the following question is explained below.
- <u><em>Therefore the temperature that is require to fill the gas is 254.3 K</em></u>
Explanation:
Given:
no of moles (n) = 3.67 moles
volume of the gas (V) = 67.5 liters
pressure of the gas (P) = 115 k Pa
To solve:
Temperature of the gas (T)
We know;
<u>P × V = n × R × T</u>
<em>Where;</em>
P is pressure of the gas
V is the volume of the gas
n is the no of the moles
R is the universal gas constant
here the value of R(universal gas constant ) is 8.314 k Pa./mole.K
We know;
115 × 67.5 = 3.67 × 8.3145 × T
T =
T =
T = 254.39 K
<u><em>Therefore the temperature that is require to fill the gas is 254.3 K</em></u>
The "mitochondria" produces ATP which is essential for active transport so it determines the rate of active transport
hope that helps
Answer: Option D) All of the above.
Explanation:
The ecosystem is made up of living and non-living component relating with their environment. i.e in an ecosystem, plants and animals relate with the food nutrients, climate and weather conditions, soil structure etc
Thus, all of the conditions: a rise in temperature; natural disaster like flooding; the introduction of a new animal species like a predator will definitely change the previously stable condition of an ecosystem.
