How many planet earths are needed to have a mole of people?
Mine- 6.0221479 x 10 ^23
1 planet earth 6 x 10 ^9
-6 x 10^9 + 6 x 10^9= 6 x 10^18
- 23-18= 5
- 6 x 10^9 + 6 x 10^9 + 6 x 10^5=6 x 10^23
equals about 2.5 earths
Class- X x 6 x10^9= 6.2 x 10 ^23
X= 6.02 x 10^23 6 x 10^9
=1 x 10^14
100,000,000,000,000
