These are two different matters entirely. The 5W30 is a Society of Automotive Engineers or SAE viscosity rating. Viscosity is basically a resistance to flow or similar to how thick the oil is at a given temperature. Synthetic concerns certain quality characteristics of the oil. For example, a product can be 5W30 and synthetic, synthetic blend or conventional oil. A more detailed article on oil viscosity is in our Detailed Auto Topics section under Oil Viscosity.
