Hiii,so the problem is ♀️
Answer:
0.034 mol (4dp)
Explanation:
Use the formula n = m/M where n= number of moles, m=mass in grams and M=molar mass in g/mol.
Therefore to find how many moles, divide the mass in grams (2) by the molar mass of sodium chloride which is 22.99+35.45
It is the electron sharing.
electronegative element + electronegative element
exemple :
O₂ , H₂
hope this helps!
