None, but if you meant centigrams, there are 497.6 of them.
4976mg = 497.6cg (10mg per centigram).*Centigrams x 10 = mg*Milligrams/10 = cg

There are 1164 milligrams of sodium in 3.00 grams of NaCl. This is because sodium accounts for about 39.3% of the mass of NaCl, so you would multiply 3.00g by 0.393 to find the mass of sodium in milligrams.
This question cannot be answered sensibly. A milligram is a measure of mass, with dimensions [M]. A centimetre is a measure of distance, with dimensions [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
