PLS Help sooner than later!!

The radius of a certain molecule is about 1.3 angstroms. One angstrom is 0.000001 cm. What is the diameter of this molecule in centimeters?

Answer 1

Explanation:

radius of a circle is half of the diameter

Diameter :D , Raduis : R

D = 2R

R = 1.4 angstrom

1 angstrom = 0.00000001 cm = 10^-7 cm

R = 1.4 * 10^-7 cm

D = 2.8 * 10^-7 cm

The Diameter is 2.8x10^-7 cm
