Let us write succinic acids as H2Suc
The first ionization is
H2Suc ----> HSuc- + H+
The seond ionization is
HSuc- ----> Suc-2 + H+
Calculate the H+ concentration of from the first ionization using pKa1.
Then, calculate the H+ concentration from the second ionization using pKa2.
Next, use the buffer equation to calculate the concentration of the salt in the solution. Then, use the given volume to get the number of moles of the salt. Finally, use the given molecular weight to get the mass.

Explanation:
Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.
Convergent: When two plates are moving towards each other.
If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.
If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.
Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.

ΔS = 0.250 J·K^(-1)
<em>Step 1</em>. Calculate the <em>moles of CO</em>
From the<em> </em><em>Ideal Gas Law</em>,
<em>n</em> = (<em>pV</em>)/(<em>RT</em>) = (8.00 kPa × 3.00 L)/(8.314 kPa·L·K^(-1)·mol^(-1) × 298.15 K)
= <em>0.009 682 mo</em>l
Δ<em>S</em> = <em>nC</em>_Vln(<em>T</em>_2/<em>T</em>1)
= 0.0096 82 mol × 20.17 J·K^(-1)mol^(-1) ln(1073.15 K/298.15 K)
= 0.1953 J·K^(-1) × ln3.599 = 0.250 J·K^(-1)
