Question

the end stage of the star whose initial mass Is 25 times larger than the mass of the sun will be​

Answer 1

Answer:

1.269×10^15 years

Explanation:

Mass of star =1.98×10^30×25=4.95×10^31g

The star would collapse into a black hole as it's mass is so huge.

time=10^10×(mass of star/luminosity of sun)

time= 10^10 ×(4.95×10^31/3.9×10^26)

time =10^10×126923.07692

time=1.269×10^15 years
