It varies with container, temperature, pressure and amount of gas. But, the volume occupied by a gas at a fixed temperature and pressure remains constant which is 22.4 L for 1 mole at STP.

2. Ultraviolet radiation has a frequency of 6.8 x 10'5Hz. Calculate the energy, in
Gnoma [55]

Answer:

E=4.5\times 10^{-18}\ J

Explanation:

It is given that, the frequency of Ultraviolet radiation is 6.8\times 10^{15}\ Hz

We need to find the energy of the photon. The formula for the energy of a photon is given by :

E=hf\\\\\text{Where h is Planck's constant}\\\\E=6.63\times 10^{-34}\times 6.8\times 10^{15}\\\\E=4.5\times 10^{-18}\ J

So, the energy of the photon is 4.5\times 10^{-18}\ J.

The mass per mole of a substance is called its molar mass.<br><br>True or false ​
tatuchka [14]

The molar mass of a substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units....

hope that helps

so i think that it is false  because base on the statement above si the decision is yours just read it thanx

Calculate the mass (in grams) of methylene bluecrystals that you must weigh in order to make 100.0mL of 1.25 × 10-5mol/L methyle
mario62 [17]

<u>Answer:</u> The mass of methylene blue that must be weighed is 3.99\times 10^{-4}g

<u>Explanation:</u>

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

We are given:

Molarity of solution = 1.25\times 10^{-5}M

Molar mass of methylene blue = 319.85 g/mol

Volume of solution = 100.0 mL

Putting values in above equation, we get:

1.25\times 10^{-5}M=\frac{\text{Mass of methylene blue}\times 1000}{319.85\times 100.0}\\\\\text{Mass of methylene blue}=\frac{1.25\times 10^{-5}\times 319.85\times 100.0}{1000}=3.99\times 10^{-4}g

Hence, the mass of methylene blue that must be weighed is 3.99\times 10^{-4}g
