So obviously there are tons and tons of
protons in the sun. The question is if
the sun were totally made of protons,
how many would there be? Well, we can
work that out by taking the total mass
of the sun 2 * 10 30 kg
and dividing by the mass of 1 proton,
which is 1.673 673
* 10 - 27
kg.
And the answer you'll find is 1.1
95*
10 ^ of 57
protons.
If the sun were totally made of protons,
that is how many would be there. That's
really an unthinkable number. It's
basically a one followed by 57 zeros.
A huge number of protons. Now, if you
don't have a calculator handy, you can
actually solve this kind of problem by
typing it straight into the Google
search field. What you need to do is put
in 2 e 30. Now, Google interprets this e
as time.
then divide by 1.673
e minus
- 27.
So if you type that straight into the uh
Google search field, you will find it'll
give you the answer 1.195
* 10 ^ of 57.
