Question

How much mass was there in the protoplanetary disk out of which the planets formed, compared to the mass of the Sun?

Answer 1

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.
