Which of the below statements regarding the relationship between mass, volume, and density is correct? If the mass of a sample increases the volume will also increase, but the density remains constant
If the volume of a sample increases the mass will decrease, but the density remains constant
lf volume of a sample increases the mass and density will stay the same.
If the mass of the sample increases the volume and density will stay the same.​

the answer is a and have a great day

so what is the problem with your lab report and whats the subject of the lab report? i will you

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.
