Answer: [tex]0.141\times 10^{-9} meters[/tex]
Explanation:
The distance between the atoms of H-Br is 1.41 [tex]\AA [/tex]
[tex]1\AA =1\times 10^{-10} meters[/tex]
Then 1.41 [tex]\AA [/tex] in meters wil be:
[tex]1.41\times 1\times 10^{-10} meters=1.41\times 10^{-10} meters=0.141\times 10^{-9} meters[/tex]
[tex]0.141\times 10^{-9} meters[/tex] has three significant figures('1','4' and '1')
