Question
The material at the center of a star has a mass density of 5.0 x 1018 kg:m3. if a sphere of this material of volume 5 m3 were somehow transported to the surface of the earth, what would be the weight of this sphere?

The material at the center of a star has a mass density of 5.0 x 1018 kg:m3. if a sphere of this material of volume 5 m3 were somehow transported to the surface of the earth, what would be the weight of this sphere?Explanation / Answer
From the information given, we need to first find the volume of this sphere, then find its mass and lastly calculate its weight. Therefore, we need the following formulas:
Weight, W = mg
Step 1- Finding the massof the sphere:
:we know that mass = ( density) (volume)
m = V, so
Step 2 - Finding the weight of the sphere:
= (5 m3)(5.0 × 1018 kg m-3)= 25 × 1018kg
