An experiment requires 45.6g of isopropyl alcohol as reagent. instead of measuring the mass of a liquid on a balance you decide to determine the mass by using an equivalent volume measured in a graduated cylinder. the density of isopropyl alcohol is 0.785g/ml. what volume of the alcohol is required for the experiment.

58.089 mL

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

density of isopropyl alcohol = 0.785 g/mL

mass = 45.6 g

volume = ?

Now we will put the values in the formula,

d= m/v

v=m/d

v= 45.6 g/ 0.785 g/mL

v= 58.089 mL

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.
