The molarity of an aqueous solution of NaCl is defined as the(1) grams of NaCl per liter of water
(2) grams of NaCl per liter of solution
(3) moles of NaCl per liter of water
(4) moles of NaCl per liter of solution
Answers
Answer:
The correct option is (4)
Explanation:
Molarity (M) is generally defined as the number of moles of a solute per liter of the solution.
The formula for molarity (from the definition above) is
M = number of moles (n) ÷ volume (in liters or dm³)
The unit for molarity is mol/L or mol/dm³
From the above, it can be deduced that the molarity of an aqueous solution of common salt (NaCl) is the number of moles of NaCl per liter of the salt solution.
Answer (4)

ANSWER: The comma attempts to separate a compound subject.
EXPLANATION: The comma is used in a sentence where a pause is necessary. In this statement, the comma is separating a compound sentence which was unnecessary. The whole sentence is joined by the word 'and' and doesn't need any other word to give a pause in the sentence.
The comma is used incorrectly in the sentence above because it attempts to join two independent clauses without a coordinating conjunction.
The sentence "The graduate students filled out the necessary applications" and "submitted the required references" are both independent clauses, each having its own subject and verb. However, the comma is not sufficient to connect these two clauses properly. To correct this, a coordinating conjunction like "and" should be used after the first independent clause, or the comma could be replaced with a semicolon. The current use of the comma creates a comma splice error, which is a common grammatical mistake.
