The molarity of the solution will be:
B. 1.5 M, this can be calculated on adding the values of V and n in molarity formula.
It is defined as the ratio of number of moles of solute by the Volume of the solution in liters.
It is given by:
Molarity = n/ V
What information do we have?
Volume = 5L
Moles of NaOH = 7.5 moles
On substituting the values
M= n/V
M= 7.5 moles / 5L
M= 1.5 M
Thus, the molarity of the solution is 1.5 M.
Hence, option B is correct.
