Math Help - Isolating variables?

1. Isolating variables?

I need to isolate n in the problem

$PV=nRT$

I tried to divide RT by both sides which leaves it like $PV/RT=n$ which looks wrong, but i think it's right. I'm not sure what else to try, since the PV is not divisible by RT How can I isolate the n?

Thanks

Why do you say that it looks wrong ? It's correct !
Did you enter it in your calculator and did it yield something wrong ?
When entering it in a calculator, don't forget the parenthesis :

$\frac{PV}{RT}=PV/(RT)$ ^^

3. I entered it wrong in the calc, so I thought it was wrong. I did leave out the parenthesis.

Thanks
