Which of the following is constant for 1 mol of any gas?

Question

a. PT/V

b. PV/T

c. VT/P

d. PVT

Answer 1

if PV = nRT

nR is constant for any gasses (n = 1, R is a constant)

nR = PV/T

your answer is b

Answer 2

PV = nRT

Pressure * Volume = # moles * Gas Constant * Temperature

Rearranges to:

PV

-----    = nR     (n = 1 mol and R is constant)

T

So (B)

Answer 3

it's (b);

Answer 4

For 1 mole of gas... it is PV/T

Which in this case is b)

This is because...

The ideal gas law is PV=nRT

Since it's just 1 mol of gas then n=1... so we have PV=(1)RT

or simply PV=RT

R is the gas constant which you are trying to find in this question so you want to isolate it... So you bring the T to the other side to get

PV/T=R

And that's how you get the gas constant for one mole of gas

(Again it's R = PV/T)

Answer 5

b. PV/T because PV/T = nR

To derive this, look at PV = nRT

Divide PV by T, which is dependent and needs to go along with pressure and volume (which are dependent as well on independent nR)

Where n = 1 mol and R is the molar gas constant

0.0821(L x atm/mol x K). R does not change just like 1 mol is constant
