Hi!
• For this you want to convert moles to grams
• To do this you would simply multiple your moles times the atomic mass of potassium
3.25 x 39.098= 127.0685
• So your answer for this should be about 127.07 depending on how you need to round!
So pH of the 1.0 * 10-2 mol-1 KOH is 12.
Answer:
<h2>50.90 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 454 g
density = 8.92 g/mL
We have
We have the final answer as
<h3>50.90 mL</h3>
Hope this helps you
Yes. it is COOH. C=O is carbonyl and OH is hydroxyl
Answer:
1. A diprotic acid was neutralized.
2. HCl has the ability to accept two protons.
Explanation:
Hello,
Neutralization chemical reactions are better quantified by using equivalent grams instead of moles since they define the mass of a given substance which will neutralize the other substance, thus, in the first, experiment, 1 mole of NaOH has 1 equivalent grams since there's just one hydroxile in its structure, on the other hand, as 2.00 L of a 1.00 M solution of NaOH were needed to neutralize 1.00 L of a 1.00 M solution of an acid, one concludes that the acid was diprotic, it means that it has two hydrogens in its structe.
In such a way, in the second experiment, it was the other way around but by using the hydrochloric acid as it has the ability to accept two protons, it means that the base had two hydroxile ions in its structure.
Best regards.
