How would you solve for n in PV=nRT?

Answer 1

Well, rearrange the formula...

#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?

#n=(PV)/(RT)#

Given #PV=nRT#

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

To solve for ( n ) in the ideal gas law equation ( PV = nRT ), divide both sides of the equation by ( RT ). This gives ( \frac{PV}{RT} = n ). So, to solve for ( n ), you would calculate the product of pressure (( P )) and volume (( V )), then divide by the product of the ideal gas constant (( R )) and temperature (( T )).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
