The density of pure gold is 19.3g/cm3. what is the volume of 1.00 g of pure gold?

Volume of 1g of pure gold

Given;

Density of a pure gold=19.3

Mass of a pure gold =1g

To find:

Volume of 1g of pure gold

Solution:

According to the formula,

Density= Mass/Volume

Where =density of pure gold

           m=mass of pure gold

          v=volume of pure gold

From the above equation volume can be calculated as

Substitute the values of mass and density value in the above equation

Result:

Thus the volume of 1g of pure gold is

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
