1. the wavelength of light is 589 nm (nano metre). wat is its orde of magnitude in metre???????( 1 nano mtre = 10 to the power of minus 1. ) i need the working and can u pleae explain too. i`ll be really thankful!
2. the radius of a hydrogen atom is 0.5 angstrom. find the order of magnitude of volume of (a) one hydrogen atom, (b) 1 mole hydrogen. given that 1 mole of hydrogen has 6.02 multipled 10 power of 23 hydrogen atoms.
(hint- volume = 4/3 pie r cube (r is the radius))
i need to know how to do it with working!!!

Do you really have to put up this question SEVEN times?
Not very Cool....

1) 1nm=10 to the power of minus 1
589nm=10 to the power of minus*5.89*10 to the power of 2
=5.89*10 to the power of 1 or 5.89*10m
for second question mail me at soodrachit@yahoo.com cos it is not possible to show you the working here.seriously
