Explanation:
I'm not sure if this is what you are looking for but i will attempt to answer.
Isotopes are variations of the same atom. They have the same number of protons but have a different number of neutrons. As a result of this, the atomic number remains the same but the mass number changes.
A calculation you could perform in relation to isotopes would be calculating the relative atomic mass. The relative atomic mass is the weighted average of masses of isotopes.
Relative atomic mass (RAM)= the addition of
For example, the element Indium has a relative isotopic mass of 112.90406, 4.29% of the time. It has a relative isotopic mass of 114.903878, 95.71% of the time.
From this
RAM=
<span>Li has fewer electrons than Li+ (protons can't change)

Explanation:
Answer:
94 moles of Carbon
Explanation:
From the question,
Using Avogadro's constant
1 mole of every element contains 6.03×10²³ atoms of the element
If 1 mole of Carbon contains 6.03×10²³ atoms of Carbon,
Then, x mole of Carbon will contain 5.67×10²⁵ atoms of Carbon
1 mole of C ⇒ 6.03×10²³ atoms of C
x mole of C ⇒ 5.67×10²⁵ atoms of C
solve for x
x = (1× 5.67×10²⁵)/6.03×10²³
x = 94.03 moles of Carbon
x ≈ 94 moles of Carbon
