Answer:
a
Explanation:
the solution is extremely acidic and will dissolve the zinc rod
V = nRT/P
V = 0.685 mol*(.0821 L*atm/K*mol)*273 K/1 atm
Note down the formula below

Mass of the compound

Mass % of Oxygen:-



The answer is A I’m pretty sure lol
Answer: Partial pressure of
at a depth of 132 ft below sea level is 2964 mm Hg.
Explanation:
It is known that 1 atm = 760 mm Hg.
Also, 
where,
= partial pressure of 
P = atmospheric pressure
= mole fraction of 
Putting the given values into the above formula as follows.


= 0.780
Now, at a depth of 132 ft below the surface of the water where pressure is 5.0 atm. So, partial pressure of
is as follows.

= 
= 2964 mm Hg
Therefore, we can conclude that partial pressure of
at a depth of 132 ft below sea level is 2964 mm Hg.
