Find :  How much (kg) of Hydrogen is reacted in the sun each second?

Given :

-- The solar flux (output) on Earth is

-- The mass of an electron is

-- Earth is 149,598,000,000 meters from the sun.

-- Earth's radius is 6,378.1 kilometers

-- Sun's radius is 695,500 kilometers

Assuming :

Note these assumptions are fairly safe if you're looking for a general figure.  They are not safe if you want an exact number.

-- The sun's energy source is totally controled by this reaction

You're such a nerd, Sidoh.

I know.  ^_^

I seriously think this problem is fascinating, though.  The figure you calculate in this problem alone was enough to really shock me.

Answer: A lot.

That's a good answer, but I need it to be much more specific.

46522.1366666667 kg. 

Nope!  It's a lot more than that.

Good, I'd be worried if it was because I totally made up that number :)

Good answer.  It's correct, but you have to PROVE it.  If I were you, I'd just find the other right answer and prove that instead.

I did it in my head, its much too complex to write it down in such a way that your primitive human mind can understand.

First you have to be willing to shed primative human notions of "numbers" and "logic"
