Answer:
7.52 × 10⁻¹⁴ mi
Explanation:
Step 1: Given data
Bond length between two carbon atoms (l): 121 pm
Step 2: Convert "l" to meters
We will use the conversion factor 1.00 m = 1.00 × 10¹² pm.
121 pm × (1.00 m / 1.00 × 10¹² pm) = 1.21 × 10⁻¹⁰ m
Step 3: Convert "l" to miles
We will use the conversion factor 1.00 mi = 1609.34 m.
1.21 × 10⁻¹⁰ m × (1.00 mi / 1609.34 m) = 7.52 × 10⁻¹⁴ mi
I know the answer it is...
