Answer:
4960000000 pm
Explanation:
4.96*1000000000= 4960000000
Answer:
Uranium atoms required to be laid side by side to span a distance of 4.96 mm is [tex]1.6644\times 10^7[/tex] atoms.
Explanation:
The radius of a uranium atom ,r = 149 pm =[tex]1.49\times 10^{-7} mm[/tex]
[tex]1 pm=10^{-9} mm[/tex]
The diameter of a uranium atom ,d =
d = 2r =[tex]2\times 1.49\times 10^{-7} mm=2.98\times 10^{-7} mm[/tex]
The let the uranium atom to be laid side by side to span a distance of 4.96 mm be x.
[tex]x\times d=4.96 mm[/tex]
[tex]x=\frac{4.96 mm}{d}=\frac{4.96 mm}{2.98\times 10^{-7} mm}=1.6644\times 10^7[/tex] atoms.
Uranium atoms required to be laid side by side to span a distance of 4.96 mm is [tex]1.6644\times 10^7[/tex] atoms.
