Answer:
The number of moles of the chemical constituents will be less than the actual amount.
Step-by-step explanation:
In calculating empirical formula, we begin with the number of grams of each element, given in the problem.
Given that the spill will affect the mass concentration of the copper chloride solution, calculations to determine the molecular formula (using Molarity = mass conc รท molecular mass ) would give a lesser result, which would in turn lower the number of moles of the copper and chloride in the empirical formula calculation.
