In a balanced, non-charged atom, the number of protons (positive charge) is equal to the number of electrons (negative charge)
So there are 92 electrons
Answer:
The answer is
<h2>0.052 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 2.5 g
volume = 48 cm³
The density is
We have the final answer as
<h3>0.052 g/cm³</h3>
