The mass of the protoplanetary disk was about $2*10^30Kg$ , the mass of the Sun is about $1.989*10^30Kg$ .

Explanation:

The mass of the solar system, and hence the protoplanerary disk, is about $2*10^30$ Kg. The Sun at $1.989*10^30Kg$ contains $99.89%$ of the solar system's mass.

Of the remaining mass the four gas giants Jupiter, Saturn, Uranus and Neptune make up $99%$ . The other $1%$ is the combined mass of the rocky planets, asteroids, comets and dust and gas.
