Density is calculated as mass divided by volume. We are given the mass of 15.0 grams, so we need to find the volume. For a cube, volume is calculated as (length of side)^3, so in this case, we have the length of a side as 44.5 mm, which is equivalent to 4.45 cm.
Volume = (4.45 cm)^3 = 88.1 cm^3
Then we divide mass by the volume:
Density = (15.0 grams) / (88.1 cm^3) = 0.170 g/cm^3
So the correct answer is A.
In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.
According to the kinetic theory of matter, the molecules that compose matter are in constant random motion. The nature of this motion varies in the three states of matter which are;
In the solid state, the molecules do not translate, they only vibrate and rotate about their mean positions. In the liquids state, the molecules translate but they still have restricted degrees of freedom due to intermolecular interactions. In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

Hello ^^
Answer:
D.Triple Bonds
Explanation:
A Triple bond is when three pairs of electrons are shared between two atoms in a molecule. It is the least stable out of the three general types of covalent bonds.
Hope this helps!
