The density of a certain type of plastic is 0.81 g/cm3. if a sheet of this plastic is 10.0 m long, 1.0 m wide, and 1 cm thick, what is its mass?
mass = x
g
enter your answer in scientific notation.

The mass of plastic sheet is

Explanation:

The plastic sheet is in the form of cuboid. To calculate the volume of cuboid, we use the equation:

where,

V = volume of cuboid

l = length of cuboid = 10.0 m = 1000 cm     (Conversion factor: 1 m = 100 cm)

b = breadth of cuboid = 1.0 m = 100 cm

h = height of cuboid = 1 cm

Putting values in above equation, we get:

To calculate mass of a substance, we use the equation:

We are given:

Density of plastic sheet =

Volume of plastic sheet =

Putting values in equation 1, we get:

Hence, the mass of plastic sheet is

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.
