Answer:
Does the wave require a medium in order to travel?
Explanation:
The question whose answer would determine whether the wave in question is mechanical or electromagnetic would be <u>if the wave requires a medium in order to travel or otherwise.</u>
<em>A mechanical wave would require a medium in order to transport its energy from one place to another, that is, travel. On the other hand, an electromagnetic wave does not require any medium in order to travel, that is, it can travel through vacuums or empty spaces</em>. <u>Light</u> and <u>sound waves</u> are typical examples of <u>electromagnetic</u> and <u>mechanical waves</u> respectively.

Answer:
The mass of solution the student should use is 23.4 g.
Explanation:
Hi there!
The concentration of the solution, 42.7% w/w, indicates that there is 42.7 g of isopropenylbenzene (IPB) per 100 g of solution. Then, if the student needs 10.00 g IPB, the mass of solution the student should take will be:
10.00 g IPB · (100 g solution/42.7 g IPB) = 23.4 g solution.
Then, the mass of solution the student should use is 23.4 g.
