Final answer:
The molarity of the NaCl solution is 2.17 M.
Step-by-step explanation:
The molarity of the NaCl solution can be calculated by converting the given mass of NaCl to moles, then dividing it by the volume of the solution in liters. Firstly, we need to convert the given mass of NaCl to moles by dividing it by the molar mass of NaCl (58.44 g/mol). So, 0.4 ft moles * 0.3048 m/ft * 31.1035 g/mol / 58.44 g/mol = 0.2066 moles of NaCl. Next, we need to convert the volume of the solution from mL to L by dividing it by 1000. So, 95.0 mL / 1000 = 0.095 L. Finally, we can calculate the molarity by dividing the moles of NaCl by the volume of the solution in liters. The molarity of the NaCl solution is therefore 0.2066 moles / 0.095 L = 2.17 M.
