The radius of a water molecule is about 1.4 angstroms. One angstrom is 0.00000001 cm. What is the diameter of a water molecule in centimeters?

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

Flippo

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
