C. 49.8 grams of ki is dissolved in enough water to make 1.00 l of solution. what is the molarity?
2 answers:
Answer:
49.8 grams of KI is dissolved in 1 L of solution have a molarity = 0.3M
Explanation:
We need the molar mass of KI, we can find the molar mass with the atomic weight of potassium and iodo. We can find this information using the periodic table of the elements.
Atomic weight of
Atomic weight of
Adding the atomic weights of potassium and iodo, we can obtain the molar mass of KI:
To find the molarity we need the moles of KI in 49.8 g of KI
The molarity formula is:
Where:
n= moles of KI
V= volume
The molarity is 0.3 M

Explanation:
When we talk about electrophilic substitution, we are talking about a substitution reaction in which the attacking agent is an electrophile. The electrophile attacks an electron rich area of a compound during the reaction.
The five membered furan ring is aromatic just as benzene. This aromatic structure is maintained during electrophilic substitution reaction. The attack of the electrophile generates a resonance stabilized intermediate whose canonical structures have been shown in the image attached.
