Answer:
The answer to your question is: # of atoms = 2.42 x 10¹⁰
Explanation:
Data
radius = 248 pm
row = 6 cm long
Conversion
1 pm ------------------- 1 x 10 ⁻¹⁰ cm
248 pm -------------------- x
x = (248 x 1 x 10⁻¹⁰) / 1
x = 2.48 x 10⁻¹⁰ cm
Divide
# of atoms = 6 / 2.48 x 10⁻¹⁰
# of atoms = 2.42 x 10¹⁰
Answer:
No
