Answer:
Explanation:
Hello!
In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution in liters, we first need to compute the moles of solute knowing that the molar mass of calcium hydroxide is 74.1 g/mol as follows:
Next, since the 100-mL solution is also expressed in liters by 0.100 L, we directly compute the molarity as shown below:
Which is expressed in molar units that are mol/L.
Best regards!
Explanation:
Formula for energy value is as follows.
E =
where, = 13.6
n = number of shell
So, at ground state energy of hydrogen atom will be as follows.
E =
=
= -13.6
Hence, for an ionized atom value of energy will be as follows.
E' =
or, E' =
Thus, we can conclude that total energy of the remaining electron in the ionized atom is .
