Viefleur [7K]

Answer:  8.24x10^5 years, or 8.24x10^3 centuries

Explanation:  Sequential conversions to arrive at a total population rate of 2.31x10^10 atoms/sec for the entire population.  Total seconds would be (6.02x10^23 atoms/2.31x10^10 atoms/sec) = 2.60x10^13 seconds.  No breaks allowed, then (2.60x10^13 seconds)/(3.1536x10^7 sec/year)= 8.24x10^5 years.
