Answer:
<h2>0.02 moles </h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
![n = \frac{N}{L} \\](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7BN%7D%7BL%7D%20%5C%5C)
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
We have
![n = \frac{1.204 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.02](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7B1.204%20%5Ctimes%20%20%7B10%7D%5E%7B22%7D%20%7D%7B6.02%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%20%20%20%20%5C%5C%20%20%3D%200.02)
We have the final answer as
<h3>0.02 moles</h3>
Hope this helps you
The answer is flourine
flourine some what sounds like flow so
flourine is a flowing element
This is a question similar to one wrestled with by Newton himself, who didn't understand why the planets didn't fall into each other. The reason satellites don't fly into space is because they are being pulled towards the planet by the planet's gravity.

Answer:
![a=123.04\ m/s^2](https://tex.z-dn.net/?f=a%3D123.04%5C%20m%2Fs%5E2)
Explanation:
Given that,
Force applied to a soccer player, F = 56.6 N
The mass of the ball, m = 0.46 kg
We need to find the acceleration of the soccer ball. The force acting on the ball is given by :
F = ma
Where
a is the acceleration
![a=\dfrac{F}{m}\\\\a=\dfrac{56.6 }{0.46 }\\\\a=123.04\ m/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7BF%7D%7Bm%7D%5C%5C%5C%5Ca%3D%5Cdfrac%7B56.6%20%7D%7B0.46%20%7D%5C%5C%5C%5Ca%3D123.04%5C%20m%2Fs%5E2)
So, the required solution is
.
Red giants produce "metals", i.e., heavier elements.
The first step is helium conversion into
