for adult human being the average heart rate vary from 60 to 100 per min.
we take the average heart rate to be 80 per min.
also general age of lifespan 72 years
total heartbeats = (80/min)(60 min/h)(24h/day)(30day/month)(12month/yr)(72yr)
=2,985,984,000
That is approx. equals to 3*109

A
generation is about one-third of a lifetime. Approximately how many
generations have passed since the year 0 AD?
The answer is 10^2 generations. I don’t understand how they
got this answer.

1. Your group will need approximately 6 g of the copper ammine complex to perform the analyses. The general formula for the copper ammine complex is [Cu(NH3)x]SO4•H2O Calculate the formula weight for several values of x, x=2 through x=6. 2. You will need to prepare about 6 g of the copper ammine product. Estimate how much CuSO4•5H2O you should start with to prepare approximately 6 g of the copper ammine complex. 3. Calculate how many grams of copper sulfate pentahydrate...
