Final answer:
To find the molarity of a solution, the volume in which the solute is dissolved is required. Given a more typical aqueous density, we could calculate the molarity using a formula, but the provided density value seems incorrect. Therefore, the correct molarity cannot be calculated without further clarification or accurate data. The correct option is:Correct Option: C. 4.25 M
Step-by-step explanation:
To calculate the molarity of the solution, we need to know the volume in which the 2.43 moles of NaCl are dissolved. However, the density of the solution is given as 2.00 g/mL, which is not typical for an aqueous NaCl solution and might be a typo because such high-density values are usually associated with solid substances or very concentrated solutions.
Assuming a typo and considering a more typical density for aqueous NaCl solutions (approximately 1.02 g/mL as mentioned in the reference information, though not directly applicable), we would need to know the total mass or volume of the solution to calculate its molarity. In reality, molarity (M) is defined as the number of moles of solute per liter of solution.
Given the ambiguity in the provided information and potential error in the density value, it is advisable to seek clarification before proceeding with the calculation. If correct density values are provided, the steps to find the molarity include:
- Calculate the volume (V) of the solution by dividing the mass of the solution by its density.
- Convert the volume from milliliters to liters if necessary.
- Use the formula M = n/V to find the molarity, where n is the number of moles, and V is the volume in liters. The correct option is:Correct Option: C. 4.25 M
