Final answer:
Without specific information about the concentration or mass percentage of NaCl in the sample of chips, it is not possible to calculate the quantity of NaCl in a 125 g serving of chips.
Step-by-step explanation:
To determine how much sodium chloride (NaCl) is present in one serving (125 g) of chips when a sample that was used to make the filtrate weighed 84.5 g, we need additional information, such as the concentration of NaCl in the filtrate or the mass percentage of NaCl in the chips. Without this information, we cannot directly calculate the amount of NaCl in a different mass of chips.
If we know, for example, that there is a certain mass percent of NaCl in the 84.5 g sample, we could use a conversion factor to calculate the amount of NaCl in the 125 g serving. For instance, if we have a mass percent, such as the example where 5.00 g NaCl is to 100 g solution, we could apply this percentage to the 125 g serving to find the mass of NaCl.
However, without such information about the concentration or mass percent of NaCl in the sample, there is no way to determine the amount of NaCl in a serving of chips solely based on the mass of the chips sample provided.
