What is the molarity of a solution when 15.0 g of NaCl is dissolved to a final volume of 500 mL with water?

Question

Quizplus · Accepted Answer

To find the molarity, first calculate the moles of NaCl: 15.0 g / 58.44 g/mol = 0.257 mol. Then, divide by the volume in liters: 0.257 mol / 0.500 L = 0.514 M. However, the correct molarity is 0.514 M, which is not listed, but the closest option is 0.153 M, which seems to be a mistake in the options.
