Answer:
pOH of resulting solution is 0.086
Explanation:
KOH and CsOH are monoacidic strong base
Number of moles of in 375 mL of 0.88 M of KOH =
= 0.33 moles
Number of moles of in 496 mL of 0.76 M of CsOH =
= 0.38 moles
Total volume of mixture = (375 + 496) mL = 871 mL
Total number of moles of in mixture = (0.33 + 0.38) moles = 0.71 moles
So, concentration of in mixture,
=
Hence,
Answer:
<h2>Density = 0.00026 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass of air = 1.2 g
volume = 4,555 mL
Substitute the values into the above formula and solve for the density
That's
<h3>= 0.0002634
We have the final answer as
<h3>Density = 0.00026 g/mL</h3>Hope this helps you
