What is the molarity when 50.0 ml of 2.0 m naoh is diluted to 150 ml?
6.0 m
0.67 m
1.0 m
1.5 m

The molarity of concentrated NaOH solution is 6 M

Explanation:

To calculate the molarity of the concentrated solution, we use the equation:

where,

are the molarity and volume of the concentrated NaOH solution

are the molarity and volume of diluted NaOH solution

We are given:

Putting values in above equation, we get:

Hence, the molarity of concentrated NaOH solution is 6 M

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 0.42 is that is an option. this question provides no info
