Answer:
<h2>0.62 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%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
From the question we have
![n = \frac{3.73 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{3.73}{6.02} \\ = 0.619601...](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7B3.73%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%7B6.02%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%20%20%3D%20%20%5Cfrac%7B3.73%7D%7B6.02%7D%20%20%5C%5C%20%20%3D%200.619601...)
We have the final answer as
<h3>0.62 moles</h3>
Hope this helps you
The given statement is True.
This is single replacement reaction.
As reactivity decreases down the group,
Iodine is less reactive than Chlorine.
And so Iodine cannot replace chlorine from FeCl2.
I2 + FeCl2 ---> no reaction (Iodine is less reactive than chlorine)
I feel like it would be O.40 mol Mgo but I could be wrong
The total charge of a compound must be zero. So the Y ion has charge of -2. Then the charge of X ion+(-2)*2=0. So the charge of X ion is +4.
It is a very acidic compound
