What is in my calculator should be the answer u might have to round to the nearest tenths place
A because when it removes it shifts left
The number of formula units of NaCl are 7. In 1 mole of NaCl there are 
formula unit are present.
Thus, 1 formula unit will be there in 
moles.
and, 7 formula unit will be there in 
moles.
There is 1 mol of Cl present in 1 mol of NaCl. thus, of Cl will be there in mol of NaCl.
Converting number of moles into number of atoms as follows:
In 1 mole of a substance there are atoms of chlorine thus, in mol there will be 7 atoms of chlorine.
Therefore, number of atoms of chlorine will be 7.
My answer would be D, 100% sure.
I hope that helps.
Answer:
Methanol is more soluble > LiCl > Br2(l) > O2(g)
Explanation:
Arrange the following compounds in order to increase water solubility:
O2 = nonpolar gas, MW(Molecular weight)= 32 g/mol
LiCl= ionic salt, dissociate in Li+ and Cl-ions Br2= nonpolar liquid;
MW= 319.4 g / molmethanol(CH3OH)= polar liquid, MW= 32 g/mol
Therefore, with this data: polar methanol comes then, remember that like dissolves like, so polar + polar will dissolve pretty good LiCl appetite. However keep in mind that it will have a "saturation" point, since then most salts will not be infinitely soluble, Br2(l); since it is a non-polar liquid, it will have low solubility, but since it is a halogen, it will have low solubility.
Methanol is more soluble > LiCl > Br2(l) > O2(g)
