Explanation:
- Electrons are negatively charged particles that orbits the nucleus.
- Chemical and physical properties of elements are usually determined by the number of electrons they posses.
- Electrons are the basis of the chemical changes in which atoms undergo.
- Chemical properties of atoms are a function of the number of electrons they posses.
- When atoms combine, they do so in order to attain stability.
- Combination of atoms involves the loss or gain or sharing of electrons between atoms.
- When atoms combine with one another, they form chemical bonds.
- These chemical bonds can be between two atoms or between molecules.
- The nature of the chemical bonds determines the physical and chemical properties of a host of compounds.
- For example, metallic bonds in metals is responsible for their conductivity and malleability.
- It is also responsible for the wide range of reactions they undergo.

Answer: The density of glycerine is
Explanation: We are given density of glycerine in which is
To convert t into , we are given conversion rates:
454 grams = 1 pound
So, 1 gram will be equal to
Similarly,
So, will be equal to
Converting the density of glycerin from to using above conversion rates, we get:
Density of glycerin is
