What is the pressure of a gas that began at 38 torr, and 500L and is changed to occupy a volume of 677 L?
qwelly [4]

Answer:

P₂ = 28.5 torr

Explanation:

Given data:

Initial pressure = 38 torr

Initial volume = 500 L

Final volume = 677 L

Final pressure = ?

Solution:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = Initial volume

P₂ = Final pressure

V₂ = Final volume

Now we will put the vales in formula.

P₁V₁ = P₂V₂

P₂ = P₁V₁ /V₂

P₂ = 38 torr × 500 L / 667 L

P₂ = 19000 torr. L / 667 L

P₂ = 28.5 torr

Calculate the ph of a 0.25M solution of monochloroacetic acid at 25 c
Phoenix [80]
<h3>Answer: <em>pH=2.25 </em></h3>

Explanation:

monochloroacetic acid  also means: chloroacetic acid

pKa of monochloroacetic acid= 1.4 x 10^-3  (I believe this should have been given in the problem or perhaps in the textbook)

Formula: pH= pKa + log ( some number in M)

pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25

pH= 2.25
