How many grams are there in a 29 grams of a 0.285m solution of 385ml

266.055 g

Explanation:

We have the following data related to this unknown substance:

are the grams of substance

is the molarity of the substance, given by the following formula:

(1)

In this case the volume of solution is

Finding the moles of solute:

(2)

(3)

Now we have to convert this to grams by the following relation:

(4)

Finding :

(5)

(6)

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.
