1st Energy
2nd Energy
3rd Energy
Generally the equation for Energy E for electron in one dimensional box at ground state is mathematically given by
Therefore Length a is mathematically given as
Answer:
The answer is
<h2>7.39 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of Mercury = 100 g
density = 13.54 g/mL
The volume of the metal is
We have the final answer as
<h3>7.39 mL</h3>
