$n = \frac{P V}{R T}$ $n=(PV)/(RT)$

Explanation:

Given $P V = n R T$ $PV=nRT$

(and assuming neither $R$ $R$ nor $T$ $T$ are zero)
$\Rightarrow \frac{P V}{R T} = \frac{n R T}{R T} = n$ $rArr color(blue)((PV)/(RT))=(nRT)/(RT)=color(blue)n$

Well, rearrange the formula...

Explanation:

$P V = n R T$ $PV=nRT$ ...when we manipulate the equation we perform the same operation ON BOTH sides of the equation...so divide each side thru by $R T$ $RT$ ...and thus...

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

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