Answer:
.4586M
Explanation:
It's simple, just devide the mol value by the volume value. So 3.66mol/7.98L=.4586M
Answer:
Option B. 25mL
Explanation:
Step 1:
Data obtained from the question:
Molarity of stock solution (M1) = 6M
Volume of stock solution needed (V1) =..?
Molarity of the diluted solution (M2) = 0.5M
Volume of diluted solution (V2) = 300mL
Step 2:
Determination of the volume of the stock solution needed.
Using the dilution formula, we can easily find the volume of the stock solution needed as follow:
M1V1 = M2V2
6 x V1 = 0.5 x 300
Divide both side by 6
V1 = (0.5 x 300) /6
V1 = 25mL
Therefore, 25mL of 6M NaOH is needed.
Answer and Explanation:
The solution to this problem are chemical structures, and they would not look good written here. Therefore, I have solved them on paper and will post the attachment to this solution.
The answer is definitely 4. It has fewer electrons. This is because, whenever the electrons are few, they are positive. Positive electrons are anions, while the negative ones are cations. Hope i helped. Have a nice day.
