A normal paraffin with a molecular weight of grams per mole has an estimated boiling point of degrees Celsius.
A normal paraffin with a molecular weight of grams per mole has an estimated boiling point of degrees Celsius.
The minimum estimated boiling point for normal paraffins corresponds to a paraffin with a molecular weight of grams per mole and an estimated boiling point of degrees Celsius.
The maximum estimated boiling point for normal paraffins corresponds to a paraffin with a molecular weight of grams per mole and an estimated boiling point of degrees Celsius.
Explanation
Correct answer: B.
Choice B is correct. It’s given that the graph shows the estimated boiling point , in degrees Celsius, of a normal paraffin with a molecular weight of grams per mole. It follows that for the point , represents the molecular weight, in grams per mole, of a normal paraffin and represents its estimated boiling point, in degrees Celsius. Therefore, the best interpretation of the point is that a normal paraffin with a molecular weight of grams per mole has an estimated boiling point of degrees Celsius.
Why the other choices are wrong
Choice A
Choice A is incorrect. This statement represents a situation where , not , represents the boiling point, in degrees Celsius, and , not , represents the molecular weight, in grams, per mole.
Choice C
Choice C is incorrect and may result from conceptual errors.
Choice D
Choice D is incorrect and may result from conceptual errors.
