This question is a dilution problem. In order to prepare a certain concentration and volume from a stock solution, you have to use the equation,
M1V1 = M2V2
From the equation, you need to calculate the volume you need from the stock solution to be able to have the diluted concentration then dilute it to a certain volume.
(1.0 M) (V1) = (0.1 M) (100 mL)
V1 = 0.1 mL is needed from the 1.0 M HCl solution
1.8x10^20 atoms x (1 mole / 6.022x10^23 atoms) = 3.0x10^-4 mole
Anything with a pH level of 3, 2, or 1.
Answer:
Ketone, alcohol and unsaturation
Explanation:
The functional groups are the groups that identify the organic function of the molecule. For example, the hydroxyl (-OH) represents alcohol, the carbonyl (represented in the figure below) can represent a ketone or an aldehyde, and so each function has its representation.
The cortisone molecule is represented below, and each group is marked in blue. They are:
a, c, and d = carbonyl of ketone;
b = unsaturation (double bond) of alkene;
e, and f = hydroxyl of alcohol.
