22. A scientist needs 12 mL of a solution. They have a bottle with 0.12 L in it. Do they have enough?
Answer: B
Yes, they have more than what they need
The scientist has 0.12 L of solution, which is equivalent to 120 mL. Since 120 mL is greater than the required 12 mL, it is clear that they have more than enough solution.
A) Yes, they have exactly what they need
This option is incorrect because the scientist has more solution than the exact requirement of 12 mL. They possess 120 mL, which exceeds the needed amount.
B) Yes, they have more than what they need
This option is correct because 0.12 L (or 120 mL) is significantly greater than 12 mL. Therefore, the scientist indeed has more solution than required.
C) No, they do not have enough
This option is incorrect as the scientist has a total of 120 mL available, which is more than sufficient for the requirement of 12 mL. Thus, this statement does not hold true.
D) None of the above
This option is also incorrect because option B accurately describes the situation. Since the scientist has more than what they need, this option does not apply.
Conclusion
The correct answer is B, as the scientist possesses 120 mL of solution, exceeding the 12 mL required. All other options fail because they either underestimate the amount available or incorrectly assert that the scientist lacks sufficient solution. Thus, B is the only accurate choice in this context.
