Answer: Well I need to know the empirical formula, molecular formula.

Then I can multiply the grams of each individual element by their molar mass, and divide the smallest element by itself, and the other elements by the smallest element. Then I get the empirical formula

The unit 1 electronvolt (1 eV) is defined as the energy acquired by an electron as it moves through a potential difference of 1 V. Suppose two states differ in energy by 1.0 eV. What is the ratio of their populations at (a) 300 K and (b) 3000 K?

Answer:

a)

b) 0.021

Explanation:

The ratio of populations (r) is given by the equation:

Where DE is the difference between the states, k is the Boltzmann constant (k = , and T is the temperature in Kelvin.

So, DE = 1 eV = J

a) For T = 300 K

r =

r =

b) For T = 3000 K

r =

r = 0.021

The ratio of their populations at (a) 300 K and (b) 3000 Kis mathematically given as

r = 1.6x10^{-17}

r' = 0.021

What are the ratio of their populations at (a) 300 K and (b) 3000 K?Question Parameter(s):

The unit 1 electronvolt (1 eV)

it moves through a potential difference of 1 V

Generally, the equation for the ratio of populations is mathematically given as

Therefore

a)

For T = 300 K

r = 1.6x10^{-17}

b)

For T = 3000 K

r' = 0.021

the pressure on a gas at -73° C is doubled but its volume is held constant. what will the final temperature in degrees be?

Answer:

127.15 °C

Explanation:

Gay-Lussac's law states that the pressure of a given mass of gas directly proportional to the absolute temperature of the gas at constant volume.

Mathematically,

P₁ / T₁ = P₂ / T₂ -----(1)

Data Given:

Initial Pressure = P₁ = 1 atm (assumed)

Initial Temperature = T₁ = -73°C = 200.15 K

Final Pressure = P₂ = 2 atm (doubled)

Final Temperature = T₂ = ????

Solving equation 1 for T₂,

T₂ = P₂ × T₁ / P₁

Putting these values;

T₂ = 2 atm × 200.15 K / 1 atm

T₂ = 400.3 K

Or,

T₂ = 127.15 °C

Conclusion:

By doubling the pressure results in increase in temperature.
