What quantity of Compound 1 must be provided to prepare 100.00 mL of solution with a concentration equal to Ki?

• A. 48.4 mg
• B. 24.2 mg
• C. 5.64 mg
• D. 2.92 mg

Answer: (D)

To determine the quantity of Compound 1 needed to prepare a 100.00 mL solution with a specified concentration (Ki), it's essential to understand the relationship between concentration, volume, and mass.

Concentration is defined as the amount of solute (in this case, Compound 1) divided by the volume of the solution. If the concentration equals Ki, then the desired mass of Compound 1 can be calculated using the formula:

[ \text{mass} = \text{concentration (M)} \times \text{volume (L)} \times \text{molar mass (g/mol)} ]

In this scenario, given that the final volume of the solution is 100.00 mL (or 0.100 L), we can compute the mass required once we know Ki and the molar mass of Compound 1.

Choosing the correct answer involves making certain this calculated mass corresponds to the provided option. The answer of 2.92 mg suggests that the calculated concentration and amount align accurately with the specified conditions.

This indicates that to achieve the proper concentration in the specified volume, the mass of Compound 1 must be precisely measured and adjusted. Thus, the option indicating 2.92 mg reflects the
