Homework Statement


If the mass of a hydrogen atom is 1.67*10-27kg and the mass of an electron is 9.1*10-31kh, how many electrons would be required to have a mass equivalent to one hydrogen atom?


Homework Equations





The Attempt at a Solution


I tried dividing them into each other but I got some weird answer which didn't seem like it was right.

1.835x10^(-28)
The 1.835 looks OK.

But 10-27/10-31 = 104 and then there is the 10-1 from the division itself.

I wonder what I did wrong.

So you are saying it is 1.835x10^3

I really dont know what I did that was wrong. The answer I submited was 1835 which was correct. I appreciate the help on such a simple question.

I took math up to calc so I should have figured that out. . . sad. . .
