Answer:
The volume of the potassium hydroxide solution was 164.1 mL
Explanation:
In the equivalence point of a titration between an acid an a base, the moles of H⁺ are equal to the moles of OH⁻.
In the case of potassium hydroxide (KOH) and hydrochloric acid (HCl), an equation that represents the equivalence point would be:
Using that equation and the data given in the problem, we can calculate the volume of potassium hydroxide:

Hello!
To determine the Kb of gallic acid is actually very simple.
The
dissociation reaction of Gallic Acid (HGal) is the following:
HGal+H₂O ⇄ H₃O⁺ + Gal⁻The equation for converting from Ka to Kb is the following:
So, the Kb is
2,19*10⁻¹²Have a nice day!
Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.
The density of the gas can be given by the mass of the substance and its volume. A 4084 gms of ammonia has a volume of 5.99 L.
<h3>What is STP?</h3>
STP is the condition at which the temperature and the pressure of the gas are at the normal and standard conditions.
The density of the ammonia = 681.9gm/L
The mass = 4084 gm
The volume is calculated as:
V = Mass ÷ Volume
= 4084 ÷ 681.9
= 5.99 L
Therefore, at STP the volume of ammonia is 5.99 L.
