The pressure of the vessel at a temperature of 25 °C is 106.73 KPa
We'll begin by calculating the number of mole of fluorine gas. This can be obtained as follow:
Mass of F₂ = 6.40 g
Molar mass of F₂ = 19 × 2 = 38 g/mol
<h3>Mole of F₂ =? </h3>
Mole = mass / molar mass
Mole of F₂ = 6.40 / 38
<h3>Mole of F₂ = 0.168 mole </h3>
Finally, we shall determine the pressure. This can be obtained as follow:
Volume (V) = 3.90 L
Temperature (T) = 25.0 °C = 25 + 273 = 298 K
Mole of F₂ (n) = 0.168 mole
Gas constant (R) = 8.314 L.KPa/Kmol
<h3>Pressure (P) =? </h3>
PV = nRT
P × 3.9 = 0.168 × 8.314 × 298
P × 3.9 = 416.232096
Divide both side by 3.90
P = 416.232096 / 3.90
<h3>P = 106.73 KPa </h3>
Therefore, the pressure of the vessel is 106.73 KPa

Answer:
Explanation:
Raoult's law is a tool that allows to determine vapour pressure of solutions. The formula is:
<em>(1)</em>
Where
P is Pressure of solution and solvent and X is mole fraction.
Moles of solute and solvent are:
Biphenyl:
11.5g×(1mol /154.21g) = <em>0.0746mol</em>
Benzene
31.9g×(1mol /78.11g) = <em>0.408mol</em>
Mole fraction of benzene is:
= <em>0.846</em>
Replacing in (1):

The information given in the question is not enough to determine the acidity of the solution. This is because, acidity can only be found with the equation: pH = -log [H+].
In order to determine the acidity of the solution, the half titration point value is needed, this will make it possible to determine the value of H30+. If the half point titration value is known, then Ka will be equivalent to pH and the value will be evaluated using the equation: - log (1.6 * 10^-10).
Answer:
No
Explanation:
In my opinion water doesn't evaporates when is spills on a fabric or a shirt someone is wearing. The fabric or cloth whatever you may call it sucks the water, making you feel your shirt wet. But as the time passes it will slowly dry due to the sun or the warmth surrounding the area the fabric is at.
Answer:
96 m/s.
Explanation:
Distance equals speed x time,
12 x 8, so the distance is 96 m/s.
