A solution of acetic acid and water contains 205.0 g L-1 of acetic acid and 820.0 g L-1 of water. Compute the density of the sol

LekaFEV [45]

Answer:

$\rho_t=1025000 gmL^{-1}$

Explanation:

From the question we are told that:

Density of acetic acid $\rho_a=205 gL^{-1}$

Density of Water $\rho_w=820 gL^{-1}$

Generally the equation for Solution Density is mathematically given by

$\rho_t= \rho_w+\rho_a$

$\rho_t=205+820$

$\rho_t=1025 gL^{-1}$

$\rho_t=1025000 gmL^{-1}$

Calculate the energy of an electron in the n = 2 level of a hydrogen atom.

ANEK [815]

Answer: The energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.

Explanation:

Given: n = 2

The relation between energy and $n^{th}$ orbit of an atom is as follows.

$E = - \frac{13.6}{n^{2}} eV$

Substitute the values into above formula as follows.

$E = - \frac{13.6}{n^{2}} eV\\= - \frac{13.6}{(2)^{2}}\\= - 3.40 eV$

The negative sign indicates that energy is being released.

Thus, we can conclude that the energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
