Answer: a) 0.579 atm
b) 0.585 bar
c) 58662 Pa
Explanation:
Pressure of the gas is defined as the force exerted by the particles on the walls of the container. It is expressed in various terms like 'mmHg', 'atm', 'kiloPascals' etc..
All these units of pressure are inter convertible.
We are given:
Pressure of the gas = 440 mmHg
a) Converting this unit of pressure into 'atm' by using conversion factor:
![760mmHg=1atm](https://tex.z-dn.net/?f=760mmHg%3D1atm)
![440mmHg=\frac{1}{760}\times 440=0.579atm](https://tex.z-dn.net/?f=440mmHg%3D%5Cfrac%7B1%7D%7B760%7D%5Ctimes%20440%3D0.579atm)
b) Converting this unit of pressure into 'bars' by using conversion factor:
![760mmHg=1.01bar](https://tex.z-dn.net/?f=760mmHg%3D1.01bar)
![440mmHg=\frac{1.01}{760}\times 440=0.585bar](https://tex.z-dn.net/?f=440mmHg%3D%5Cfrac%7B1.01%7D%7B760%7D%5Ctimes%20440%3D0.585bar)
c) Converting this unit of pressure into 'Pascal' by using conversion factor:
![760mmHg=101325Pa](https://tex.z-dn.net/?f=760mmHg%3D101325Pa)
![440mmHg=\frac{101325}{760}\times 440=58662Pa](https://tex.z-dn.net/?f=440mmHg%3D%5Cfrac%7B101325%7D%7B760%7D%5Ctimes%20440%3D58662Pa)
the answer your looking for is a because it latterly says it right there. look closer to what its asking you
(Missing in your question ):
we have the following reaction:
A(aq) ↔ 2 B(aq)
and Kc = 7.02 x 10^-6 at 500K
So at equilibrium,
Kc = [Products] / [ reactants]
= [B]^2 / [A]
we have [A] = 3.3 m and Kc is given= 7.02 x10^-6
by substitution:
7.02x10^-6 = [B]^2 / 3.3
∴[B]^2 = 2.3 x 10^-5
∴[B] = 0.005 m
2.34 moles titanium x (6.022 x 10^23)/1 mole titanium = 1.41 x 10^24
