The best way to represent the concentration of a 1.75 M K2CrO4 solution is 1.75% K2CrO4 (option A).
<h3>What is molarity?</h3>
Molarity is the concentration of a substance in solution, expressed as the number moles of solute per litre of solution.
The molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.
The molarity is measured in mol/L or M, hence, it can be said that the molarity of a solution is 0.1M.
However, the concentration of a solution is best represented by using %. In accordance with this question, the best way to represent the concentration of a 1.75 M K2CrO4 solution is 1.75% K2CrO4.

<span>Body fossils can mostly be found in things like rocks and minerals deep in the ground or in mountains and caves. They can also be found in quick drying substances such as for example tar pits or basically anywhere where there has been historically chance of encountering a fossil. You can also find them in peat, so that's 4 then.</span>
Answer:
0.2 Litres
Explanation:
There are 1000 milliliters in a liter so 200 millimeters is equal to (200/1000) 0.2 litres.
Not quite sure what type of answer you were looking for but I hope this hoped anyway!
