Answer:
10²¹  stars
Also,
answer to the nearest whole power of 10 by entering the exponent only will be 21
Explanation:
Data provided in the question:
The total mass of a particular galaxy = 10āµā¹ grams
The Average mass of the star in the particular galaxy = 10³ⓠgrams
Now,
The number of stars in that particular galaxy will be
= [The total mass of a particular galaxy ] Ć· [Average mass of the star in the particular galaxy]
= 10āµā¹ grams Ć· 10³ⓠgrams
= 10ā½ āµā¹ ⻠³ⓠā¾
= 10²¹  stars
Also,
answer to the nearest whole power of 10 by entering the exponent only will be 21
