Answer:
The answer to your question is the mass of solute = 53.5 g
Explanation:
Data
mass of solution = 482 g
mass of solute = ?
mass percent = 11.1 %
Mass percent is a unit of concentration. It measures the mass of the solute divided by the total mass of the solution
Process
1.- Write the formula
Mass percent = mass of solute / mass of solution x 100
-Solve for mass of solute
mass of solute = Mass percent x mass of solution / 100
2.- Substitution
mass of solute = 11.1 x 482 / 100
3.- Simplification
mass of solute = 5350.2 / 100
4.- Result
mass of solute = 53.5g
Answer:
A Fridiel craft catalyst will convert benzene to acetophenone.
Permanganate catalyst can be used to convert toluene to acetophenone.
Explanation:
Benzene can be reduced to acetophenone by the addition of anhydrous aluminium chloride, AlCl₃
The mechanism is as follows:
Benzene + Acetyl choloride → acetophenone
To convert toluene to acetophenone, the following steps are necessary:
- Oxidation of Toluene to Benzoic acid.
This is done by refluxing toluene with alkaline potassium permanganate (KMnO₄+ Na₂CO₃).
-
Benzoic acid is converted to Benzoyl chloride by treating with thioyl chloride and heating at about 80 ⁰C.
-
Benzoyl chloride is treated with methyl lithium to form Acetophenone.
Answer:
2. Co(NO3)2 + H2
Explanation:
Hello,
In this case, we are evidencing a simple displacement reaction wherein the cobalt is able displace the hydrogen to produce cobalt (II) nitrate and gaseous hydrogen as a result of cobalt's higher activity:
Therefore, answer is 2. Co(NO3)2 + H2.
Best regards.
