Answer:
0.674M of NaOH
Step-by-step explanation:
Molarity, M, is an unit of concentration defined as ratio between moles of solute and liters of solution.
In the problem, sodium hydroxide (NaOH) is the solute (Less quantity) that is dissolved in 3.77 liters of water, probably.
Thus, molarity of 2.54 mol NaOH in 3.77L is:
2.54mol NaOH / 3.77L = 0.674M of NaOH
