Explanation:
As a neutral lithium atom contains 3 protons and its elemental charge is given as
. Hence, we will calculate its number of moles as follows.
Moles = 
= 
= 100 mol
According to mole concept, there are
atoms present in 1 mole. So, in 100 mol we will calculate the number of atoms as follows.
No. of atoms = 
=
atoms
Since, it is given that charge on 1 atom is as follows.

= 
Therefore, charge present on
atoms will be calculated as follows.

Thus, we can conclude that a positive charge of
is in 0.7 kg of lithium.
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>
Hope this helps you
