Question

How would you solve for n in PV=nRT?

Answer 1

`n=(PV)/(RT)`

Explanation:

Given `PV=nRT`

(and assuming neither `R` nor `T` are zero)
`rArr color(blue)((PV)/(RT))=(nRT)/(RT)=color(blue)n`

Answer 2

Well, rearrange the formula...

Explanation:

`PV=nRT`...when we manipulate the equation we perform the same operation ON BOTH sides of the equation...so divide each side thru by `RT`...and thus...

`(PV)/(RT)=n(RT)/(RT)=ncancel((RT)/(RT))=n`

So `n=(PV)/(RT)`...Happy?
