A 1.75 gram perfect cube of wood has a side measure of 2.45 cm, what is the density of the wood?

0.119 g/cm³

Explanation:

Step 1: Given data

Mass of the cube (m): 1.75 g

Side measure (l): 2.45 cm

Step 2: Calculate the volume of the cube

We will use the following expression.

V = l³

V = (2.45 cm)³

V = 14.7 cm³

Step 3: Calculate the density (ρ) of the cube

The density of the cube is equal to its mass divided by its volume.

ρ = m/V

ρ = 1.75 g/14.7 cm³

ρ = 0.119 g/cm³

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.
