How many moles of silver would you have if you have 550 g of silver?

5.1 mol

Explanation:

Silver's molar mass is 107.8682

550/107.8682=5.09881503539

Or if you round it's = 5.1

5.0

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

it is the most commonly accepted one
