Formula units are there in 212 grams of MgCl₂ are 830.56
Formula is the empirical of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations and it is the lowest whole number ratio of ions represented in an ionic compound
Here given data is
MgCl₂ = 212 grams
1 mole of magnesium chloride has mass = 95.211 gram and contains 6.022×10²³formula units of magnesium chloride
Here 212 grams×6.022×10²³form unit of MgCl₂/95.211 gram = 830.56

Answer:
Inside the nucleus, the attractive strong nuclear force between protons outweighs the repulsive electromagnetic force and keeps the nucleus stable. Outside the nucleus, the electromagnetic force is stronger and protons repel each other.
Explanation:
Answer: a) The
of acetic acid at
is 
b) The percent dissociation for the solution is 
Explanation:

cM 0 0

So dissociation constant will be:

Give c= 0.10 M and
= ?
Also ![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
![[H^+]=1.35\times 10^{-3}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1.35%5Ctimes%2010%5E%7B-3%7DM)
![[CH_3COO^-]=1.35\times 10^{-3}M](https://tex.z-dn.net/?f=%5BCH_3COO%5E-%5D%3D1.35%5Ctimes%2010%5E%7B-3%7DM)
![[CH_3COOH]=(0.10M-1.35\times 10^{-3}=0.09806M](https://tex.z-dn.net/?f=%5BCH_3COOH%5D%3D%280.10M-1.35%5Ctimes%2010%5E%7B-3%7D%3D0.09806M)
Putting in the values we get:


b)
