Explanation:
It is given that the initial mass of benznene is 7.9286 g
Mass of benzene left = 5.9987 g
So, mass of benzene with which gas get saturated will be calculated as follows.
= 7.9286 g - 5.9987 g = 1.9299 g
Therefore, moles of benzene with which gas get saturated = 
= 
= 0.0247 moles
Temperature = 
= 27.3 + 273.15 = 300.45 K
Volume = 5.01 L
So, according to ideal gas equation PV = nRT
Putting the given values into the ideal gas equation as follows.
PV = nRT
= 
P = 
= 92.371 torr
Hence, we can conclude that vapor pressure of benzene is 92.371 torr.

Below is the solution:
pOH = - log (5.75 × 10^−4) = 3.24
<span>pH = 14 - 3.24 = 10.76</span>
If the student forgot to calculate 12 H2O molecule from the compound, that means the compound molecular mass used will be much lower than it should. If the molecular mass calculated lower than it should, then the percent yield would be increased.
If the student fixes the compound mass, then the yield will become lower than the first result.
Answer:
Explanation:
Hello!
In this case, since we have 245 of iron (III) oxide, we first need to compute the moles contained there:
Now, as 1 mole of iron (III) oxide is related to 2 moles of iron, due to iron's subscript in the molecule, we get the moles of iron itself:
And the mass is computed based on the atomic mass of iron:
Best regards!
B) Volcano
As a landslide, an earthquake, and a geyser are all of a result of other factors other than the crust being ruptured.
