Final answer:
To calculate the mass of NaCl in the mixture, we need to use the molar mass of NaCl and the density of the solution. However, the question lacks sufficient data to perform this calculation, such as the volume of the solution or the total mass of the mixture.
Step-by-step explanation:
The question requires us to calculate the mass of NaCl in a mixture using the data provided regarding solubility and molarity. To find the mass of NaCl, we need to consider the molar mass of NaCl, which is 58.44 g/mol, and use the given density of the solution, which is 1.02 g/mL. There are inconsistencies and missing data in the question provided, thus it is not possible to calculate the exact mass of NaCl without additional information such as the volume of the solution or the total mass of the mixture before dissolution.
