An electron confined in a one-dimensional box is observed, at different times, to have energies of 12 eV, 27 eV, and 48 eV. What

Fynjy0 [20]

Answer:

$l=3.5*10^{-10}m$

Explanation:

From the question we are told that:

1st Energy $E_1=12eV=4(3eV)$

2nd Energy $E_2=27eV=9(3eV)$

3rd Energy $E_3=48eV=16(3eV)$

Generally the equation for Energy E for electron in one dimensional box at ground state $E_0$ is mathematically given by

$E_0=\frac{h}{8ml^2}$

Therefore Length a is mathematically given as

$l=\sqrt{\frac{h^2}{8mE_0} }$

$l=\sqrt{\frac{(6.625*10^{-34})^2}{8(9.1*19^{-31}{(3eV(1.6*10^{-19}))}}$

$l=3.5*10^{-10}m$

Solve the equation for n 0.0092=0.608 x (n/84.01)+n/52.5

kotegsom [21]

Answer:

$n\approx 0.350$

Explanation:

1. Rewrite the equation in a more appropriate format for a better understanding:

$0.0092=0.608\times \dfrac{n}{84.01}+\dfrac{n}{52.5}$

2. Multiply the whole equation (both sides) by 84.01 × 52.5 to eliminate the denominators:

$0.0092\times 84.01\times 52.5=0.608\times 52.5n+84.01n$

3. Do the operations:

$40.57683=31.92n+84.01n$

4. Add like terms:

$40.57683=115.93n$

5. Divide both sides by 115.93:

$0.350011\approx n\\\\n\approx 0.350011\\\\n\approx 0.350$
