#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#

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?
