A student prepares a solution by dissolving 60.00 g of glucose (molar mass 180.2 g mol-1) in enough distilled water to make 250.0 mL of solution. The molarity of the solution should be reported as
a. 12.01 M
b. 12.0 M
c. 1.332 M
d. 1.33 M
e. 1.3 M

1.332 Molar is the molarity of the glucose solution.

Explanation:

Molarity of the solution is the moles of compound in 1 Liter solutions.

Mass of glucose = 60.00 g

Molar mass of glucose = 180.2 g/mol

Volume of the solution = V = 250.0 mL = 0.250 L

(1 mL  = 0.001 L)

1.332 Molar is the molarity of the glucose solution.

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.
