Use the information on the endpapers of this book to calculate the average density of Sun.Question PartPointsSubmissions Used Solution sun diameter is about 1,400,000 km so 0.25 solar masses in 8e-6 of the volume means it is about 2 million times the suns average density 1/2 an AU is about 75 million km , assuming it is spherical then 1/(0.4*(7.5e7/7e5)^3) is not much more than 2 millionths of the current average density of the sun..
