4.86 is the answer to you're question.
<span>The 6 means we round the 7 up to the next number which is 8. Thus, we round 4.76 to </span>4.8
The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables or numbers.
The magnitude of the second atom relative to the first = magnitude of second atom / magnitude of first atom
The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100
