Answer:
How do you calculate the average atomic mass of three isotopes?
To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together. Whenever we do mass calculations involving elements or compounds (combinations of elements), we always use average atomic masses
Explanation:
Answer:
true because the bonds cannot be broken down
Answer:
Explanation:
Assume Ksp of 
=
( it is general value ,i took it because not given in question)
molar solubilty means how much maximum mole of lead thiocynate is dissolved in one litre of solvent.
Ksp=solubility product;
Lets molar solubilty of 
is S then
![[Pb^{+2}]=S;](https://tex.z-dn.net/?f=%5BPb%5E%7B%2B2%7D%5D%3DS%3B)
![[SCN^{-1} ]=2S;](https://tex.z-dn.net/?f=%5BSCN%5E%7B-1%7D%20%5D%3D2S%3B)
