Your answer is C. Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water.
Answer:
A) 29.9g
Explanation:
first find the weight of 1 staple.
then multiply with 225
The the exact mass is 24.740% (according to the internet) but I’d say that it’s 25
You must know the concentration of the acetic acid. Suppose the concentration is 0.1 M. The solution is as follows:
CH₃COOH → CH₃COO⁻ + H⁺
I 0.1 0 0
C -x +x +x
E 0.1 - x x x
Ka = (x)(x)/(0.1 - x)
1.8×10⁻⁵ = x²/(0.1 - x)
Solving for x,
x = 1.333×10⁻³ = H⁺
pH = -log[H⁺] = -log(1.333×10⁻³)
pH = 2.88
