Answer to Question #305590 in General Chemistry for mmm

Question

there are 1.699E22 atoms in 1.000 g of chlorine. Assume that chlorine atoms are spheres of radius 0.99 Å (Angstrom) and that they are lined up side by side. How many miles in length is the line of chlorine atoms? *

Answer 1

There is no use of the amount of chlorine.

The radious of Cl atom is 0.99 Å

Therefore the diameter must be 2×0.99

= 1.98 Å

For 1.699E22 atoms of Cl = 1.98 ×1.699E22

= 3.36402E22 Å

=3.36402E12 m

=2.085E9 mile ( 1m = 0.00062 mile)
