What does it mean when say that a 200-ml sample and a 400-ml sample of a solution of salt have the same molarity? In what ways are the two samples identical? In what ways are these two samples different?

Answers

Answer 1

Answer:

Answer:

Read explanation.

Explanation:

Molarity is a unit used to measure the $(solute)/(solution)$ ratio per unit volume of the solution. So, in other words, and in our case, we call it the $(moles~of~salt)/(per~ml~of~solution)$ ratio.

So, the amount of solute (moles of salt) per ml of solution will be the same, but the number of moles in each solution will be obviously different.

Answer 2

Answer:

(1) The samples of a salt solution are identical because they have the same amount of solute dissolved in them.

(2) The samples are different because the volume of their solution is different.

What is molarity?

Molarity is a measure of the concentration of a solute in a solution. It is defined as the number of moles of solute dissolved in one liter of solution.

That is, molarity quantifies the amount of the solute in a given volume of the solution.

Molarity (M) = Moles of Solute / Volume of Solution (in liters)

Thus, when it's stated that a 200-ml sample and a 400-ml sample of a solution of salt have the same molarity, it means that both samples have an equal concentration of salt molecules per unit volume, while molecules each sample have different volume.

The speed of light is 3.00×108m/s. How long does it take for light to travel from Earth to the Moon and back again?

Answers

The variable we have to determine for this problem is the time. Since the given information is speed, we have to know the distance so that we can solve for the time. From literature, the distance between the Earth and the moon is 384,400,000 meters. Therefore,

Speed = Distance/Time
Time = Distance/Speed
Time = 384,400,000 m/ 3×10⁸ m/s = 1.28 seconds
