The concentration of acetic acid in the vinegar is found to be 0.5857 M.
<u>Explanation:</u>
Here one mole of acetic acid is used to neutralize one mole of sodium hydroxide. According to the law of Volumetric analysis, we can write the equation as,
V1M1 = V2M2
V1 and M1 being the volume and molarity of NaOH
V2 and M2 being the volume and molarity of CH₃COOH
M2 = 
= 
= 0.5857 M
So the concentration of acetic acid in the vinegar is 0.5857 M.
Answer: Option (C) is the correct answer.
Explanation:
The degree of randomness or disorder is known as entropy. This means that more randomly or rapidly the molecules of a substance are moving in a container or in the Universe more will be its entropy.
For example, gases move more rapidly that solids or liquids and hence gases have high entropy.
Therefore, we can conclude that entropy measures disorder.
Answer:
The rates of decay of radioactive elements
Explanation:
The age of a rock in years is called its absolute age. Geologists find absolute ages by measuring the amount of certain radioactive elements in the rock. When rocks are formed, small amounts of radioactive elements usually get included.
I would say c . isotope mass both varies in neutron numbers and its weighted by its relative abundance to give the average atomic mass. <span />
