Accuracy is how close a value is to its true value. An example is how close an arrow gets to the bull's-eye center. Precision is how repeatable a measurement is. An example is how close a second arrow is to the first one (regardless of whether either is near the mark).

00 ml of 0.425 m h2so4 solution is required to completely neutralize 23.9 ml of koh solution. what is the molarity of the koh so

Allushta [10]

00 mL? I believe that you have erroneously pasted the question here.

Anyway, let us continue computing for the molarity of KOH but i will just use a variable “A” for the volume of H2SO4 solution.

The complete balanced reaction is:

H2SO4 + 2KOH --> K2SO4 + 2H2O

We see that 2 moles of KOH is needed for every mole of H2SO4. So calculate the moles of H2SO4.

moles H2SO4 = 0.245 M * (A / 1000) = 2.45x10^-4 A

So the number of moles of KOH is:

moles KOH = 2.45x10^-4 A * 2

moles KOH = 4.90x10^-4 A

So the molarity of KOH is:

Molarity KOH = 4.90x10^-4 A / (0.0239 L)

Molarity KOH = 0.0205 * A

Simply multiply 0.0205 by the correct volume of H2SO4 in ml

What form of energy is water flowing down a hill? *

kkurt [141]

B, If a force pushes the rock, it rolls down the hill because of the force of gravity. The potential energy is converted into kinetic energy until it reaches the bottom of the hill and stops. The water in a reservoir behind a hydropower dam is another example of potential energy.
