How many ml of cranberry juice is required to prepare a 10 ml 16% cranberry solution using a 20% cranberry stock solution?

8 mL of cranberry juice is required to prepare a 10 mL 16% cranberry solution using a 20% cranberry stock solution.

Explanation:

Let the volume of the 20% cranberry stock solution be x

Volume of cranberry juice in x volume = 20% of x = 0.2 x

Desired volume of 16% cranberry solution = 10 mL

Volume of cranberry juice in 10 mL = 16% of 10 =

Volume of cranberry juice in x volume = Volume of cranberry juice in 10 mL

0.2 x = 1.6 mL

x = 8 mL

8 mL of cranberry juice is required to prepare a 10 mL 16% cranberry solution using a 20% cranberry stock solution.

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.  

i think it is true since you can test the answer and can use observations to complete it.
