Answer:
1.67 L
Explanation:
Molarity is the molar concentration of a solution, which is NaCl solution in this case. It can be calculated using the following formula:
Molarity (M) = number of moles (n) ÷ volume (V)
According to the information given in the question:
number of moles of NaCl = 15mol
Molarity of solution = 9M
Molarity = n/V
9 = 15/V
9V = 15
V = 15/9
V = 1.67 L
