Explanation:
Scientific experiments have several types of variables. The independent and dependent variables are the ones usually plotted on a chart or graph, but there are other types of variables you may encounter.

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
