I believe it’s 32, I might be wrong though
The answer is B because none of the other options are true.
Answer:
Explanation:
Hydrosulfuric acid (H_2S) is considered a 'weak acid." It dissociates in water according to this reaction: H_2 S(aq) + H_2O(t) HS^-(aq) + H_3O^+(aq) k_a = 9 times 10^-8 Hydroiodic acid (HI) is considered a "strong acid".
Answer:
32.6 %
Explanation:
Given data
- Mass of sucrose (solute): 22.8 grams
- Mass of water (solvent): 47.1 grams
Step 1: Calculate the mass of the solution
The mass of the solution is equal to the sum of the mass of the solute and the mass of the solvent.
m(solution) = m(solute) + m(solvent)
m(solution) = 22.8 g + 47.1 g
m(solution) = 69.9 g
Step 2: Calculate the percent-by-mass of sucrose in the solution
We will use the following expression.
