Answer :
Final answer:
To solve this problem, we used the concept of dilution and the formula 'C1V1 = C2V2' to get the result of 'V1 = 143.8 mL', hence the answer is C) 143.8 mL.
Explanation:
The question revolves around the concept of dilution and the formula 'C1V1 = C2V2', where 'C1' represents initial concentration, 'V1' is the initial volume, 'C2' is the final concentration, and 'V2' is the final volume. Using this formula and replacing the densities and unknowns with the figures given in the question, we get '10.0 V1 = 2.0 x 718.7'. Solving this equation gives us 'V1 = 143.8 mL', so option C) 143.8 mL is the correct answer.
