Explanation:
Molarity is defined as the the number of moles present in a solution divided by volume in liters.
Mathematically, Molarity = 
As it is given that number of moles present into the solution are 2.00 moles and volume is 4 liter. Therefore, calculate the molarity of solution as follows.
Molarity =
= 
= 0.5 M
Thus, we can conclude that the concentration of given solution is 0.5 M.
Due to high evaporation rate and low precipitation, the oceanographer to find the highest salinity at the tropics.
<h3>What is salinity?</h3>
Salinity refers to the salt content of a water body such as rivers and oceans.
Oceans and seas have high salinity due to the presence of many dissolved minerals.
Different area of the oceans have different salinities.
Salinity is highest at the tropics and equator due to high rate of evaporation and low precipitation.
Therefore, the oceanographer to find the highest salinityat the tropics.

First by getting moles of salicylic acid:
moles of salicylic acid = molarity * volume
= 0.02 * 0.05 L
= 0.001 mol
then moles of base KOH = molarity * volume
= 0.02 * 0.055L
= 0.0011
when total volume = 0.05 + 0.055 = 0.105 L
[salisalic acid] = moles / total volume
= 0.001 / 0.105
= 0.0095
[KOH] = moles / total volume
= 0.0011 / 0.105
= 0.01
by using H-H equation, we can get the PH:
PH = Pka + ㏒[salt/acid]
by substitution:
PH = 2.97 + ㏒[0.01 / 0.0095]
= 2.99
