Answer:
pH= 3.30
Explanation:
Hydrochloric acid is a strong acid that completely dissociates in water.
For a 0.00050 M HCl solution the concentration of the hydrogen ions, [
H
+
]
, is 0.00050 moles/liter (i.e. 0.025 M).
The pH is defined as −
log
[
H
+
]
.
Substituting 0.00050 into the equation for pH we find that the 0.00050 M HCl solution has a pH of -log(0.00050) = 3.30.
Answer:
3750 cm.
Explanation:
You multiply the three side measurements to find the volume.
25cm·10cm·15cm
375cm·10cm
3750 cm.

Also, I saw you added me as a friend and I'm kinda curious as to why :)
Answer:
(a) 
(b) 
Explanation:
Hello,
In this case, since the both gases behave ideally, with the given information we can compute the moles of He in A:
Thus, since the final pressure is 3.60 bar, we can write:
The moles of helium could be computed via solver as:
Or algebraically:
In such a way, the volume of the compartment B is:
Finally, he mole fraction of He is:
