Answer:
The molarity of a solution is "25 M".
Explanation:
The given values are:
Moles of solute,
= 12.5 g
Volume of solution,
= 500 mL
i.e.,
= 0.5 L
Now,
The molarity will be:
= 
On substituting the values, we get
= 
= 
You could consider building an irrigation system.
The mass of MgCl2 is 95.211g/mol so one mole equals 95.211 it’s asking for the mass of 2.3 which is 218.9853
Answer is: MgF₂, magnesium fluoride.
Magnesium fluoride is salt, ionic compound, because magnesium is metal from 2. group of Periodic table of elements and has low ionisation energy and electronegativity, which means it easily lose valence electons, fluorine is nonmetal with greatest electronegativity, which meand it easily gain electron, so magnesium cation (Mg²⁺) and fluorine anion (F⁻) are formed.
The correct answer is 9.7 grams because mg are 1,000 difference to grams.
