The Universe is 16 billion years old. What is the age of the Universe in moles of seconds?
-------------------------------------------------------
answers:
Captain Matticus, LandPiratesInc say: The universe isn't that old, but okay, we'll play along.
1 year = 365.25 days, roughly.
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
16 * 10^(9) years * 365.25 days/year * 24 hours/day * 60 minutes/hour * 60 seconds/minute =>
16 * 365.25 * 24 * 60 * 60 * 10^(9) seconds =>
1.6 * 3.6525 * 2.4 * 6 * 6 * 10 * 100 * 10 * 10 * 10 * 10^(9) seconds =>
504.9216 * 10^(1 + 2 + 1 + 1 + 1 + 9) seconds =>
5.049216 * 10^(2) * 10^(15) seconds =>
5.049216 * 10^(17) seconds
1 mole = 6.02 * 10^(23)
5.049216 * 10^(17) / (6.02 * 10^(23)) =>
(50.49216 * 10^16 / (6.02 * 10^23)) =>
8.3874019933554817275747508305648... * 10^(-7)
The universe would need to be about 1.2 million times older than it currently is in order to have experienced 1 mole's worth of seconds.

say: Using 13.8 billion years as the age of the universe, and 6.023 x 10²³ as Avogadro's number, I find that the answer is approximately 7.230531e-7 mole second, or
.00000007230531 mole second

GREETER AT WALMART.

Idealist say: The universe isn't that old.

radu say: it depends when are you asking the question... now?... now? ...now?... :)

sepia say: One mole of anything is 6.022 × 10^23 units of that thing.
So to convert 6.022 × 10^23 seconds to years, you need to use conversion units.
60s = 1 min. 60 min = 1hour. 24 hour = 1 day. 365.242199 days = 1 year (from google)
Now we multiply these such that all units cancel out and we are left with years.

Krishnamurthy say: In physical cosmology, the age of the universe is the time elapsed since the Big Bang. The current measurement of the age of the universe is
13.799 ± 0.021 billion years within the Lambda-CDM concordance model.
-
Henry say: Good thing it's really only 6000 years old.
-
Sky say: The universe is estimated to be about 13.8 billion years old, not 16 billion. And a mole is a measurement of atoms in chemistry, not a measurement of time.
-
say: Less than 1. Convert 16 billion years to seconds. It's going to be far less than 6.022 * 10^23 seconds.
