Calculate the volume of 42.0 kg of a substance whose density is 8.96 g/ml. express your answer in milliliters using the correct number of significant figures. do not enter your answer using scientific notation.

4687.5 mL

Explanation:

Given that the density of the substance = 8.96 g/mL

Mass = 42.0 kg

The conversion of kg into g is shown below as:

1 kg = 1000 g

So, mass = 42.0 ×  1000 g = 42000 g

Volume = ?

So, volume:  

The volume of the 42.0 kg of the substance = 4687.5 mL

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.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
