The answer is D, do you want me to show you how?
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.

Answer:
a. C. volumetric flask
b. B. Measure out x mL using a volumetric pipet
c. 168.75mL
d. B. Add the correct amount of stock solution then fill to the 250 mL mark with water.
Explanation:
- The volumetric flask is mainly used in analytical chemistry to contain standard solutions or to prepare dilutions of a certain concentration of a reagent.
- The volumetric pipette is used to deliver a given volume with greater precision and accuracy.
- To make a dilution, the formula C1*V1 = C2*V2 is used where C is the concentration of the solution, in this case of molarity. V is the volume of the solution in ml and terms 1 and 2 correspond to the concentrated and diluted solutions respectively.
