Answer:
1.119 liters
Explanation:
There are 1000 millileters in 1 liter.
There are 1119 ml in this problem
Since we know that there are 1000 ml per 1 liter, we must divide the amount of millileters by 1000
1119 ÷ 1000 = 1.119 liters
Answer: The percent dissociation of 4-chlorobutanoic acid is 21%
Explanation:
The dissociation of weak acid is shown as:
cM 0 0
So dissociation constant will be:
Give c= 0.54 mM = and = ?
Putting in the values we get:
Thus the percent dissociation of 4-chlorobutanoic acid is 21%
