A solution contains 0.2 moles of hydrochloric acid. The volume of the solution is 100cm3. What is its concentration in mol/dm³?
Umnica [9.8K]
Answer= 2 mol/dm^3

Explanation:-
Firstly, we convert the volume, which is in cm^3 to dm^3. To do that divide number in cm^3 by 1000:
100/1000= 0.1 dm^3

Formula for concentration is:
Concentration= No. of moles/ Volume

So,
Concentration= 0.2/0.1

Answer= 2 mol/dm^3

In each reaction box, place the best reagent and conditions from the list below.
Serggg [28]
This is a two step step reaction as shown below,

Step 1:
           Epoxidation of Alkene:
                                              In first step Cyclohexene is treated with peroxybenzoic acid in the presence of Dichloromethane which results in the formation of epoxide moiety.

Step 2:
           Nucleophillic Substitution Reaction:
                                                                  In second step the epoxide formed is treated with Sodium Methoxide which acts as a nucleophile and attacks the less hindered carbon of epoxide resulting in the formation of final product as shown below.
