Answer:
<h2>1.264 × 10²⁴ molecules</h2>
Explanation:
The number of molecules can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 2.10 × 6.02 × 10²³
We have the final answer as
<h3>1.264 × 10²⁴ molecules</h3>
Hope this helps you
Answer: You can have a loop in a series circuit than a parallel circuit
Explanation: You can have a loop! How is this loop helpful? I don't know, I have no idea how this would be useful. Ah! maybe you can have many things activate sequentially like a lightshow. You can make a series circuit and it will just repeat. You can repeat a lightshow. I don't know what else you can do.
