Answer:
9.7 × 10² g NaF.
Explanation:
Molarity is defined by the amount of solute (mols) over the volume of solution (liters):
We want to create 6.3 liters of a 3.6 molar solution of NaF.
Solve for the amount of NaF necessary:
Therefore, about 23 moles of NaF is required.
Convert from moles to grams. The molecular weight of NaF is 41.99 g/mol:
Therefore, about 970 grams of NaF is needed to create the solution.
Answer:
Only one atom are bonded to the central atom in the .
Explanation:
Fluorine most electronegative element.
The atomic number of fluorine is 9.
Electronic configuration -
Hence, it required only one electron to get noble gas[Ne] electronic configuration.
In the molecule two fluorine atoms are bonded by single covalent bond to get stability.
Each atom share one electron and form a bond.
The structure of molecule is as follows.
