Explanation:
Although the information for the trial was not given, we can offer a summed-up reply in that while playing out an analysis to accomplish outright zero temperatures, the worth won't ever match the specific worth.
What is absolute zero?
Absolute zero is the lower furthest reaches of temperature. Considered the coldest conceivable temperature that can exist. Nonetheless, any endeavor to arrive at this temperature in a controlled climate has fizzled, researchers don't think reproducing this temperature is conceivable.
In this way, we can affirm that the worth of indisputably the zero tests didn't match the acknowledged worth. Assuming the speculation was that it would be troublesome or difficult to accomplish, then the information would uphold the theory, if not, it would neglect to do as such.
In outline, outright zero is a temperature that can't be reproduced in a lab, so the worth in this analysis doesn't match the acknowledged worth and there could be no further investigation to be done on this.
<span>If it is known that at 60 °C and 745 torr UF₆ is present only as a gas then we can make the assumption that:
</span>(n/V) = P/RT = (745 torr)/(62.36 L-torr/mol•K)(337 K) = 0.0354 mol/L
Therefore the density will be:
<span>
Density = (352.02 g/mol)(0.0354 mol/L)/(1000 cm³/L) = 0.0125 g/cm³

As per Le Chatelier principle, when a system in equilibrium is disturbed, the reaction will try to compensate the change to restore the equilibrium.
This reaction occurs in gas phase, so the volume is inversely proportional to the pressure.
Then a decrease in volume will cause an increase in pressure, so the system will tend to react in the direction that compensates this increase, this is the system will try to reduce the number of moles of particles to reduce the increase of the pressure.
As you see, there are 3 particles of products (2 of NO and 1 of Br) for every 2 particles of reactant (NOBr).
That means, that the equilibrium will displace to the left, this is the concentration of NOBr will increase while the concentration of NO and Br will decrease.
Answer:
0.25 mol
Explanation:
Use the formula n=N/NA
n= number of mols
N = number of particles
Nᵃ = Avogadros constant = 6.02 x 
So, n= 
The 10 to the power of 23 cancels out and you are left with 1.505/6.02, which is approximately 1/4. This is the same as 0.25 mol.
Hope this helped :)
First convert grams to moles:
90.0g *(mole/39.997) = 2.250mole
Remember that molarity is moles per liters:
2.250mol/3L = .750 M
