A scientist needs 12 mL of a solution. They have a bottle with 0.12 L in it. Do they have enough?

Rationale

Yes, they have more than what they need.

The scientist has 0.12 L of solution, which is equivalent to 120 mL. Since this amount exceeds the required 12 mL, the scientist indeed has more than enough solution for their needs.

A (Yes, they have exactly what they need) YOUR ANSWER

This option incorrectly suggests that the scientist has precisely 12 mL. However, since 0.12 L translates to 120 mL, there is a surplus rather than an exact match to the requirement.

B (Yes, they have more than what they need) CORRECT

The scientist needs 12 mL, and having 0.12 L (or 120 mL) exceeds that requirement. Thus, this choice accurately reflects the situation, confirming that the available solution is indeed sufficient.

C (No, they do not have enough) YOUR ANSWER

This statement is incorrect as it implies the scientist has less than the required 12 mL. Given that 0.12 L equals 120 mL, the scientist has significantly more than enough solution for their needs.

D (None of the above) YOUR ANSWER

This choice is misleading as it suggests that the previous options do not accurately describe the situation. However, option B clearly states that the scientist has more than enough solution, making this choice invalid.

Conclusion

The scientist requires 12 mL of solution and possesses 0.12 L, which converts to 120 mL. This surplus confirms that they have more than enough to meet their needs. Understanding volume conversions is essential in determining sufficiency in such scenarios, reaffirming the accuracy of option B.
