3). The D line or yellow line of the metal sodium has a wavelngth of 5.89 * 10^-7 meter. If one (1) millimicron equals 1*10^-9 meter, express the wavelength of the D line in micromillions.
Thank you very much!!!

You can put this solution on YOUR website!
Expressed in units, you have
millimicrons/wavelength = (meters/wavelength)(millimicrons/meter)
Let m = millimicrons/wavelength
m+=+%285.89%2A10%5E%28-7%29%29%281%2A10%5E%28-9%29%29
m+=+58.9%2A10%5E%28-16%29
In scientific notation:
m+=+5.89%2A10%5E%28-15%29 answer
