Answer:

The average kinetic energy of a gas depends only on its temperature.

Explanation:

The average kinetic energy of particles in a gas can be found using the equation

$\displaystyle \text{Average K.E.} = \frac{3}{2}k\cdot T$ ,

where

$k$ is the Stefan-Boltzmann constant, and
$T$ is the absolute temperature of this gas (the one in degree Kelvins.)

As seen in this equation, the average kinetic energy of particles in a gas depends only on the temperature of the gas. Also, since the question is asking for the average not the total kinetic energy, the number of particles in this gas doesn't matter, either.

How many grams of Na2SO4 should be weighed out to prepare 0.5L of a 0.100M solution?

Nezavi [6.7K]

Answer:

7 gram of Na2SO4 should be required to prepare 0.5L of a 0.100 M solution.

Explanation:

First of all the molecular weight of Na2SO4 is 142.08 gram.Now we all know that if the molecular weight of a compound is dissolved in 1000ml or 1 litee of water then the strength of that solution becomes 1 M.

According to the given question we have to prepare 0.100 M solution

1000 ml of solution contain 142.08×0.1= 14.208 gram Na2SO4

1 ml of solution contain 14.208÷1000= 0.014 gram

0.5L or 500ml of solution contain 0.014×500= 7gram Na2SO4.

So it can be stated that 7 gram of Na2SO4 should be required to prepare 0.5L of a 0.100M solution.
