A50.0 ml urine sample has a mass of 50.7 g. what is the specific gravity of the urine sample?

1014

Explanation:

Specific gravity is also known as relative density, which is the ratio of the density of a substance to a reference substance usually water.

density = mass/volume

mass of urine = 50.7g

volume of urine = 50mL

density of urine =  

                          =1014g/L

density of water = 1g/L

specific gravity of urine sample = 1014/1

                                             = 1014      

Its a dimensionless quantity as the units cancel out

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.
